Context: While the network file is disconnected, it's considered non-existent and might to be deleted.
The reason of crash:
"doClose" on the same buffer happens twice while users clicks X button, then chooses "No" when they are asked whether if this file should be kept in editor.
Explanation:
When user clicks X button on the tab of the file in question to close it, "activateBuffer" is called, then "fileClose" is called.
* activateBuffer: Following "activeateBuffer" call in the depth, "checkFileState" is invoked - that leads the message "The file "xxxxxx" doesn't exist anymore. Keep this file in Editor?". If user clicks on No, "doClose" will close the tab and destroy the buffer.
* fileClose: in "fileClose" call, "doClose" will be invoked and try to close the already-destroyed buffer.
Solution:
Retrieve the buffer ID once again, after "activateBuffer" call, for comparing with old buffer ID. If the buffer was destroyed, the new retrieved buffer ID is not the same.
Note: this commit fixes the crash, but it doesn't fix the misbehaviour: If user clicks on "Yes" to answer the message "The file "xxxxxx" doesn't exist anymore. Keep this file in Editor?", the tab will be still closed.

Refactoring for reducing the I/O calls, fix typos.
Reduce the startup time (while the a dirty disconnected network file is in the session) from about 12-15 seconds to about 6 seconds (on my laptop).
Note that there are 2 cases are not improved by the commit:
* STR 1: Open a network file, modify it. Disconnect the network, then save the file.
There will be a huge hanging time (around 1 minute) to get the warning dialog.
I tried to remedy with thread for CreateFileW in the constructor of Win32_IO_File, however it leads crash due to the lock guard in the caller.
* STR 2:
1. Open a network file.
2. Close Notepad++ to have it in the session.
3. Disconnect the network, and launch Notepad++ immediately.
4. Around more than 1 minute's delay, then the "Error" dialog displayed.
The reason of hanging is that the network file was detected by "doesFileExist" as true, so Notepad++ was trying to open non-existent file (by _wfopen).
I believe that there's some kind of cache during the very short period for the IO function (here's our case GetFileAttributes), and such cache is not immediately synchronized (cleared) while network disconnected. As a result, when we launch Notepad++ after the disconnection of network, GetFileAttributes keeps its memory & responds "FileExists". However for _wfopen it doesn't see the resource of network anymore - that makes hanging.

The issue is due to WinAPI's GetFileAttributes function can take a huge amount of time in various situations, like when the target server being offline (usalally).
The current solution is to wait at least 3 seconds for each GetFileAttributes function, then return the default value in case of the problem (or the returned value of the function, in case of normal situation - if it has been executed completely during the 3 seconds).
So there'll still be the hanging time (3 or 6 seconds) while the problem of network connection, but the hanging time (it could be 30 seconds more) is reduced considerablly.
"Wow64EnableWow64FsRedirection" call is also removed from x64 build (in which this call is unnecessary) in this commit to reduce the IO calls.

Note: while create the new tab (empty & clean), there will be a created time displayed. When the document is modified and period backup feature is enabled, a new created time will be assigned and displayed. However, the time of the first modification which makes empty document dirty will be remained as the tab creation time, even with several modification afterward.

Fix Notepad++ Debug binary crash issue while opening some special files (crash after some "Assertion fail" message boxes).
Only the Debug binary is impacted. There's no issue for the release binary, so it's not a "security vulnerability".
Also there's no buffer overflow as the description in CVE-2014-9456.

Add new plugin notification NPPN_NATIVELANGCHANGED when the native language has been changed, and add new plugin message NPPM_GETNATIVELANGFILENAME for plugins calling after getting NPPN_NATIVELANGCHANGED notification.
Usage of the command:
#define NPPM_GETNATIVELANGFILENAME (NPPMSG + 116)
// int NPPM_GETNATIVELANGFILENAME(size_t strLen, char* nativeLangFileName)
// Get the Current native language file name string.
// Users should call it with nativeLangFileName as NULL to get the required number of char (not including the terminating nul character),
// allocate commandLineStr buffer with the return value + 1, then call it again to get the current native language file name string.
// wParam[in]: strLen is "commandLineStr" buffer length
// lParam[out]: commandLineStr recieves all copied native language file name string
// Return the number of char copied/to copy
Usage of the notification:
#define NPPN_NATIVELANGCHANGED (NPPN_FIRST + 31) // To notify plugins that the current native language is just changed to another one.
// Use NPPM_GETNATIVELANGFILENAME to get current native language file name.
// Use NPPM_GETMENUHANDLE(NPPPLUGINMENU, 0) to get submenu "Plugins" handle (HMENU)
//scnNotification->nmhdr.code = NPPN_NATIVELANGCHANGED;
//scnNotification->nmhdr.hwndFrom = hwndNpp
//scnNotification->nmhdr.idFrom = 0; // preserved for the future use, must be zero

Improve Styler Configurator modification application performance considerably.
While one of dockable Panels (Folder as Workspace, for example) is loaded heavily, any action (checkboxes & comboboxes) on Styler Configurator reacts very slowly - for example, check "Bold" in "Font Style".
This commit makes difference among the operations, and optimizes each action in Styler Configurator.
