Functions defined at the top of the file or below a class with nothing in between would not show in the Function List.
This changes the function regex to fix this. A small unit test that the old regex won't pass but the new will included.

New "functionList" will be added beside of notepad++.exe or "%APPDATA%\Notepad++\", according the installation mode. If the portable package is used, after removing "doLocalConf.xml", the "functionList" folder should be copied manually from Notepad++ installed directory to "%APPDATA%\Notepad++\" to make function list work again.
All splited files are localized in this folder with the explicit language name.
"overrideMap.xml" is optional for overriding the default functionList parse rule files, and for adding UDL parse rule files.
