FMod - Fixing small bugs

I recently fixed a few small bugs in Abiathar:

• Export Image used to fail if an automatic naming pattern was specified and the dependency file had not yet been written to disk. Now, it ignores the problematic placeholders if necessary.
• An extra Tools menu used to be left behind when closing a project when Simultaneous Tileset was on. I added a bit of code to the close routine to reset all the menus to how they originally appear.
• The title bar used to show "<new project>" after using Project Settings even on a saved dependency file. That bar is now updated correctly after reloading the edited project.
