- Add a base64 decode function using Windows CyptoAPI
- Move multibyte to widechar conversions to a function
- Add config name to caption of password dialogs to help user
identify the request
- Add new dialog template for generic password/PIN requests
and use it to handle dynamic challenge
Note 1: if dynamic challenge response verification fails, an auth-failed
message is returned by the server causing the GUI to clear any saved
password even if the user-auth dialog itself succeeeded.
Note 2: Dialog template ID_DLG_CHALLENGE_RESPONSE added to language
files may require translation.

- Replace allow_password by a runtime check that enables password
change menu only when the user has write-access to the key file.
- Read exe_path and priority from HKLM and do not duplicate in HKCU.
- Always allow the user to view the config: edit will succeed if user
has write access.
- Always include the proxy settings tab which is the default.
- Remove the unused power event handling and disconnect_on_suspend key.
- Remove password_attempts -- user can stop the password dilaog
by clicking cancel.
- Remove allow_service: implicitly enabled if service_only is used.
- Deprecate removed options in cmd-line parser
- Update README.rst
- Close config file before exit in GetKeyFileName
- Close thread and dialog handles in passphrase.c

- Username and, optionally, password as well as the private
key passphrase are saved in config-specific registry keys
- All saved data are kept encrypted using DPAPI
- The passphrase dialog is skipped if a valid saved private
key password is available. However, the user-auth dialog
is always presented, prefilled with the saved username
and password.
Note: A text string "Save password" is added to three dialogs
in all language resource files. Additional text with ids
IDS_MENU_CLEARPASS and IDS_NFO_DELETE_PASS are added to the
STRINGTABLE only in the English language resource file.
All these need translations.

- Encode empty string to empty string
- If Base64Encode returns null do not pass it to snprintf
- Use the actual length of encoded string

When a connection is attempted using a config in a location
that would fail, offer an option to add the user to the "OpenVPN
Administrators" group. This is done using shell-execute which will
show a UAC prompt for elevation. If it fails (due to user chooses
NO or the UAC dialog fails) the connection is not started.
v2 Changes
- Rebase to master
- Automaticlaly add the admin group if it doesn't exist
- Allow unicode strings in debug output
- Use domain\username to identify user
- Fix the PrintDebug macro
Minor changes based on user feedback
- Bring the window back to foreground after UAC prompt completion
- Show a message if another connection is tried during authorization
- Do not add user to ovpn_admin_group if it is same as the built-in admin group

Connecting to a named pipe server while running with admin rights is not
secure in some windows versions. As the interactive service is not required
to set routes while running as admin, this looks like a safe compromise.
Fix based on feedback from Heiko Hund
- Move IsUserAdmin() check before opening the service pipe

Proxy settings are fetched from the users Internet Options
for the active connection. If WPAD or a PAC script is configured
they are preferred and used for automatic proxy detection.
Proxy bypass configuration is completely ignored.
