Move compass compilation into django_compressor

For greater reliability, move compilation of sass/compass entirely into
django_compressor, using COMPRESS_PRECOMPILERS.  Remove compilation from
the "./fromage.py" command.
Begin migrating away from lettuce

Start the process of migrating tests away from lettuce, toward the
standard LiveServerTestCase.  Moving forward, all the tests in
`scanblog/btb/features` should be refactored as LiveServerTestCase tests
in `scanblog/btb/tests/live/`.
Add refactored comment tests
Add refactored flagging and frontend tests
Add transcription tests
Mod upload tests
Add scan tests
Clean up test suite runner
Add mod users and live from web tests
Add incoming tests
Remove lettuce and fromage; update docs

Complete the move away from ``lettuce`` for tests by removing lettuce
tests, removing the `fromage.py` wrapper, and updating the documentation
to reflect the changes.

Tests are now all "native" Django tests, and all asset compilation is
handled by django_compressor.
