Changed Makefile to package object files and headers in a tarball. Also fixed a bug where uniform vectors were populated through the glUniformMatrix* functions instead of the glUniform* functions.
Changed sstGenerateDrawableSet to take in a draw mode.
Added ability to do indexed draws with glDrawElements. Also changed the name of sstGenerateDrawableSet to sstDrawableSetArrays to better fit the fact that there are now two functions to generate drawable sets.
Removed some commented-out code from examples 2 and 3.
