JJ: Add in author profiles to things that are tracked by sessions.

Summary:
Added code on /libs/ui/KisSessionResource.cpp
Now it saves the session with the authorProfile

Changed /libs/ui/KisViewManager.h

Now the following functions are public:

void changeAuthorProfile(const QString &profileName);
void slotUpdateAuthorProfileActions();

Test Plan: I compiled it, and it works, loads the session with the profile selected.
