Handle arriving FileOpen events while the launchscreen is active, cleaned up some code, make static MainWindow handling more robust. Fixes #972
bugfix: When saving an unmodified file using Save As, the file wasn't actually saved
update the previous fix: SCN_SAVEPOINTLEFT() is only accessible in QScintilla >= 2.8, always save the file on actionSave()
Calling signals from outside is only possible with Qt5. This is probably the wrong hack anyway
bugfix: Attempted to assign temporary variable to a const&, broke in debug mode. Fixes #980

Retain selection after comment/uncomment (fixes #986).
Bumped CGAL to 4.5
Fix status handling for docked windows.

Especially for the case where the windows are docked as tabs in the
same position, the "visibility-changed" signal does not work as close
indicator. The window is also treated as invisible when just the tab
is invisible, not only in case the window is closed.
Ensure window is visible after restoring the window state (fixes #976).
