v0.7-beta

Added progress bar to clock taskbar icon
Re-organised VNyan and MIU connectors into standalone classes, ready for potentially adding more streamer software in future
(0.7a) reverted a temporary debug change I made that accidentally allocated twice as much VRAM as needed
(0.7b) Removed dependency on OpenGL = faster start and a significantly smaller EXE (< 4mb)

Made the demo font spacing less ugly
