Newer in-development engine + misc.

This engine is basically being rewritten ground-up in order to be smaller and more streamlined.

Like the old engine, it is using a voxel system. Will also use a reimplemented version of the BGBScript VM.

This also contains an MSP430 emulator and basic electronics simulator.

Primary development environment: VS2015 Shell + MinGW tools (make).

deeptail0.c: Current main interface for 3D voxel engine.

isotest0.c: Small experiment for doing an isometric game.

plattest0.c: Platformer experiment.

btactst0.c: Originally a test for BTAC, now it is the asset bundling tool.

bsvm2: BGBScript2 VM.

resource: Directory for bundled/deployed assets. Bundled assets use the BtPAK format.

resource_dev: Directory for in-development assets.

base: General core code (GL/VFS/...);

voxel: Stuff related to the voxel terrain system.

entity: Stuff related to entities (mostly glue for the BS2 script code).
