Use the VBO monitor renderer by default

Browse Source 
Historically, the VBO was an order of magnitude slower than the TBO
renderer. However, as of fccca22d3f, the
difference is much smaller now. While TBOs /are/ still faster, this only
has a measurable impact in extreme stress tests, and so isn't worth the
occasional issues which occur.

I'm still keeping the code around for now: I'm incredibly fond of it,
even three years later. I may end up re-evaluating this the next time
Minecraft's rendering code changes :D.

This also adds a line to the debug screen showing the current monitor
renderer, though maybe less useful now that almost everyone will be
using VBOs!
