Add ClientInfo

This allows an app to ask a few things from the client.

1) How many objects the client is tracking. This is useful
for a quick way to check that you're freeing resources.

While the developer could use client.objects.length or
client.packs[ii].objects.length that wouldend up creating 
hundreds of thousands of NPObjects.

2) Check if the software renderer is being used

3) Check the approximate amount of memory used by textures.
Again, they could compute this with 
client.getObjectsByClassName('o3d.Texture') but it seemed
like it might be useful.

I say approximate because I would have to dig down into
the indivdual renderers to get better info since a NPOT
card will use more memory but it didn't seem worth it.

4) check the approximate amount of memory used by hardware
buffers.
