Use SCSS instead of LESS

Convert all of Horizon's styles from LESS to SCSS, and use pyscss and
django_pyscss to compile them.

This lets us continue with the upgrade to Bootstrap 3, and the use of
django_pyscss also lets us include horizon's style files, with all the
variables, in plugins style files.

This partially implements the blueprint bootstrap-update.
