The new behaviour of loading function list will be:
1. For the installer package:
Try to load from %APPDATA%\Notepad++\functionList\, if it failed, then load from %PROGRAMFILES%\Notepad++\functionList\.
In this way, users can override function list in %APPDATA%\Notepad++\functionList\ manually. Otherwise, function list won't be empty.
2. For the portable package:
- with doLocalConf.xml : Load always from <Notepad++ Dir>\functionList\
- without doLocalConf.xml : Try to load from %APPDATA%\Notepad++\functionList\, if it failed, then load from <Notepad++ Dir>\functionList\
