horizon replaced nodejs by a python alternative

since commit a0739c9423a4c559b45af96fa4cdb30539dcdbd7 and the Havana
release, horizon uses a pure Python alternative to nodejs.

Horizon changed the way to use the compress utility, the option
offline_compress is no longer available.
Thanks to Maxime Vidori for the information.

Adds COMPRESS_OFFLINE option to local_settings

The Ubuntu Havana packages includes pre-compressed
assets and does not install a package that provides
lesscpy.

This re-adds COMPRESS_OFFLINE=True to utilize this
and avoid a broken Horizon install on Ubuntu.
