proposal for Issue #1853 and ...another one

[gwenchailleu]

You can see that there is a strange ""santesocial" added to UpdateManager.cs. This is the way we hardcoded something we really needed : our app root must be under %LOCALAPPDATA%\santesocial and not under %LOCALAPPDATA% itself. A specific issue has been created about it by someone else ( not totaly sure) What is certain is that we wont be able integrate the official project until this is fixed too.
