reason we're removing the submodules (intead of keeping them around
for offline development) is that derby does some watchfile magic on the
public directory, and it causes a "max file limit" operating system
error (mitigated by `ulimit -u 2048`). For offline developers, you may
want to have some symlinks and a git stash handy
instead compile in with the css. index.coffee directives are run
against static pages too, which overwrites our bootstrap
responsive (which we need) with the app's custom responsive styles. We
may change this, but for now this commit allows us to keep the
marketing site and main site styles separate
