Added some graphical files
Working on the menu bar, but it's not going well
The menu bar seems solid, and is responding correctly

What I've essentially done without realizing it is create drop down boxes,
and used those as part of the menu bar. This isn't a bad thing, but both
systems need to be separated and hardened. However, I'm happy with my
progress so far.

The next stage is to hook the buttons up to the program itself, which
shouldn't be too difficult.
Codebase update: made Image more defensive
Working on ideas for the GUI
Fixed a derp with transparency
Refactored MenuBar, it's now fully functional

This seems solid enough for general use, and may in fact be the first part
of several GUI modules. Although the menu bar will be a massive help in
the future, I still need several other modules before I can get back to
the editor proper. I've planned about a week ahead, so I know I just need
to work at it.

The menu bar still needs to be hooked up to the rest of the code, it's
fine as it is. I feel as though planning ahead might actually be a _good_
thing. Who knew?
