The Makefile removes this automatically, but compass watch won't do that
for you. Much better to just .gitignore it so we don't have to worry
about it.
See resources/mediawiki.ui/sourcefiles to see what I mean, and see
https://www.mediawiki.org/wiki/Agora/Engineering#Working_with_the_Compass_code
for documentation about the current approach.
