FIXED:
+ typing in the console should no longer move the "player"
+ the "player" now starts at position (0, 0, 0) instead of being offset

ADDED:
+ there's a new "cube" command which you can use to make a cube. The command takes as args: MESH_NAME, MATERIAL_NAME, X, Y, Z ----> `cube foo mat_voxels 0.0 0.0 0.0` Note that right now only the "mat_voxels" material is valid, but there's no error checking, so expect it to crash if you specify a non-existent material.
+ there's a new "help" command which lists the commands available
+ there's a new .clang-format file in the top level for use with clang-format (http://clang.llvm.org/docs/ClangFormat.html)

REMOVED:
- a cube is no longer generated in the center of space-- use the "cube" console command to make one

REFACTORED:
* improved the README.md; removed outdated screenshot, fixed spelling, improved instructions
