[daala] Early results with new PVQ code

Hi,

Here are some early results I got on subset1 with the new PVQ code I've
been working on. It can be enabled simply by changing:
mbctx.run_pvq[pli] = 0;
to
mbctx.run_pvq[pli] = 1;
in encode.c.

It seems to be performing very slightly better than scalar, which is a
good sign at this point considering it just started working at all.

Cheers,

	Jean-Marc
