do portable link rewriting on import and add test to confirm it
add portable link rewriting on clone. Added tests.
add ability to rewrite links on the old /courses/<org>/<course>/<run>/jump_to/i4x://<org>/<course> .. intracourseware linking to the new portable /jump_to_id/<id> format
add test files
also support a link rewriting on course import and clone for the following format /courses/[org]/[course]/[run]/. We just need to substitute in the new course-id.
change regex names to better reflect what the actually match on
add another test. Seems like we never had an explicit test on an import into a new course-id. This fixes that
add a few debug messages to get localhost debug information. Also partition out the MongoDjangoToolbar configuration into a separate env config. This is because doing imports on large courses grinds localdev to a halt due to all the stack trace generation.
address PR feedback
fix wrapping, but mainly want to kick off another build due to Jenkins problem
resolve last code violation
on the new envs configuration file, we need to squelch pylint errors on the from dev import *
