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.

"overrideMap.xml" is optional for overriding the default functionList parse rule files, and for adding UDL parse rule files.
