ANTIRUINS v080 (Physics)

I quietly released this version last week but haven,t posted the CHANGELOG so here it is:

• Complete physics engine rewrite. The physics are now handled in the C instead of Lua.
• Supports AABB and Circle collision.
• Handles SOLID, CROSS and BOUNCE responses.
• You can now se the pitch of audio.WAV samples.
• Initial keyboard support (check input_tester.lua example)
• Set/Get Pixel for VRAM texture. (pixel.lua example)
• Fixed some bug in the sprite animation, you should now use sprite.setFrame() to set you appropriate frame number.
• There are new scripts in the tools folder, one is to match the palettes of your .dtex file to reduce palette usage.
• Added a MacOS version of mkdcdisc, haven’t tested it myself.
