move css generation into model

The model now has a css column, and when it's flushed, it generates the css
for the fields and templates. This means we don't have to generate the CSS on
deck load anymore.

The hex cache has also been removed. Javascript couldn't handle big ints, but
since ints are small numbers now, we no longer need a cache to efficiently
convert an id to hex.
