#CSpect V2.16.4 changes
Will now finally tell the user to install OpenAL, and I've fixed some 4bit relative image stuff.
- Now correctly detects that OpenAL is not installed, and will message the user and disable audio
- Added "IR" register to disassembly window
- Fixed some 4bit relative sprite shape stuff
- F5 will now screen shot whatever is on screen. The Spectrum screen (pre-shader), or the debugger
- Window should now start centered on screen (or 0,0 if screen isn't big enough)
