Subject: [PATCH] GUI: Handle non-existing projects in MRU list.

If the project file in MRU list does not exist ask user if one
wants to remove the file from the list. If user agrees then the
file is removed from the list. Otherwise the file is left to the
list but not tried to open. User may have accidentally moved or
renamed the file so we give a possibility to add it back and not
just blindly removing it from the list.
