This should solve the problem of getting `nodejs: not found` when
running `paver test_js_run -s lms` in lms-shell, which cropped up in
the past few days.
I don't know why this stopped working recently, but I don't have `nodejs`
on my recently re-created devstack, and some people with an older devstack
have both. Maybe a recent node.js release got rid of an alias.
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.

The previous approach for handling NPM assets was
to symlink them into the static directory. This appeared
to cause trouble with the asset pipeline where the files
in question were not installed and then old versions were
picked up instead.
This change instead copies NPM libraries to a new
static directory so that the pipeline can consume them
as with any other file. This new directory is added to
.gitignore so that the files don't get accidentally
checked in.
