Title: Optimize PNGs in themes and as part of build process

Since we're at RC2, I'm assuming images will not be changing much.

First commit losslessly re-compresses both themes' (default and valencia) images w/ optipng, advpng, and advdef, for a savings of 17%. Every byte counts!

I've also added new build targets, "images" and "imagesmin", which will copy and recompress images as part of jQM's build process.

Fixes issue #2650.
