Release 2

Some slight optimizations and general improvements.

OpenXcom for OpenDingux

First semi-complete release of OpenXcom for OpenDingux, featuring:

• Controlling the cursor with the left stick, eliminating the need to use mouse mode
• Controlling the battlescape camera with the rightstick
• Properly named buttons in the control menu (e.g. "A" and not "LCTRL")
• Semi-sane default settings
• Mysterious bugs

I've spent a reasonable amount of time playing this now and I'm pretty happy with it. I still plan on adjusting the analog stick controls to be a tad bit smoother, to allow rebinding of the mouse button mappings, and possibly to port over OXCE for the modding support, but for now this is probably an improvement over playing the PS1 version in an emulator.
