[Qt-creator] Side Bar bug and suggestion

[Jean-Baptiste Rouault]

The two new options in projects view (Simplify tree and Hide generated files)
are not saved during Qt Creator shutdown. (I'm using 11-25 snapshot)

Could all options concerning the side bar be independent for each session ?
I'd like to have the side bar splitted with projects and file system views for 
one session and have only projects view for another session for example.

Thanks and keep up the good work :)
