changes made to 44745759.

references to the devstack settings. We should be able to use
another settings file for development and let devstack be the

This reverts commit 0f7e2373.

This basically commits the transpiled CoffeeScript JS (with minor
cleanup) and removes coffee build support.

A tiny amount of support for xblocks exists, because external users
may have xblocks with coffee. But no coffee in our tree anyway.

temporarily include pattern library node modules for sass builds [FEDX-498]

fixup tests

move migration calculation to reset test-db script

There are symlinks and file types that are not necessary to copy over
to the actual static files output, either because they are source files
that get compiled out, or because they exist only for tests. FEDX-448.

With themes enabled, this reduces the unoptimized static asset build
size from 343M to 212M. The optimized version goes from 838M to 500M.

Add lower pylint error threshold to guard against unsuccessful runs.
Increase upper pylint threshold. Add tests for pylint option parsing.
