make rgrids return grid, not tick, lines

Removed the colormap data caching--it was trying to solve a non-problem.
Upon installation, the colormap data in _cm.py is compiled into _cm.pyc,
and importing that takes negligible time.

Cache the color data to reduce startup time.
Also, cmap kwargs now accept colormap names as strings.

Revert r7307 to the mathtex branch after a dicussion on the mailing list.

User-generated colormaps are handled more easily.
