Use webGL 2 #4

I would like for the web-client to use WebGL2. I have a branch where this is more-or-less dropped in. However, Webkit (and therefore Safari) does not yet support WebGL2, and I would very much like to support Safari. This is a tradeoff though.

The main reason I would like to support WebGL2 is to make use of 32-bit integer indices into buffers. 16-bit indices really don't leave me much room. So, we'll see how long I can make do with the 16-bit limit and how much work it will take to split assets and such.

As it turns out, another thing to look forward to is instancing. This seems to be only possible through a webGL extension right now: ANGLE_instanced_arrays. This will be a huge win for the point and line drawing systems.

I may explore using that extension in the meantime though, it looks like it has a high adoption rate:
