Also copy over alarms in instance_create().
Trivial changes that don't affect anything. Just wanted to keep everything from the compo.
Changes needed for compiling Windows.
Strangely, the cross-compiler doesn't work great with C++11 (for Apple)> Fortunately, we don't use it for anything serious (yet).

First try at a GIF loader.

Conflicts:
	ENIGMAsystem/SHELL/Universal_System/backgroundstruct.cpp
	ENIGMAsystem/SHELL/Universal_System/image_formats.cpp
Major re-write; images load faster and bit-math is speedy.
Fixed a few bugs; most GIFs found in the wild will now load.
Better error reporting, integrated Josh's suggestions, and moved a few dubiously-named variables around.
