Title: Add "Staff types..." item to "Edit" menu.

Also set initial mscore state in MuseScore constructor right before showing the window to initially enable/disable menu items which depend upon the presence of a score.

Please review the new code for the added menu item (file mscore/musescore.cpp, MuseScore::cmd(), lines 4401-4412).
