Add --random option to Lettuce

Django 1.5 compatibility - no AdminMediaHandler import

When passing -r or --random to the lettuce executable, we run both
features, and scenarios within features in a pseudo-random order.

This is helpful to detect issues that may arise from tests that
cause significant side-effects, the detection of locks etc

Fixes issue #280: don't attempt to import Django's AdminMediaHandler, and ask the user to disable LETTUCE_SERVE_ADMIN_MEDIA on Django >=1.5

Fix CLI exit code

The 'lettuce' CLI, after a successful test run, was always exiting with
an exit status of 1 indicating an error. The main() function was
erroneously considering the test run a failure if the TotalResult
instance returned by runner.run() evaluated to True (which is always
does).

This issue was reported on the mailing list [1] by Dave Sykes. I ran
in to the same problem while running lettuce from tox which reports the
success/failure of a test run based on the exit status of the test
command (lettuce).
