✨(project) re-install local libs for development

Installing OpenEdx local libraries as eggs requires modifying OpenEdx
sources (e.g. to create an egg info directory for each library). Hence,
for development as the sources are mounted as a volume, we need to
ensure that python will find related modules by reinstalling them in
the development's virtualenv.

Concerning the front-end, we also need to install specific node modules
once installed (e.g. edx-ui-toolkit) at least for the eucalyptus
release.
