All my pipeline/media changes require lessc and babel to be installed in the
local environment. This change adds the relevant command to prepare-dev to try
to prevent some of the inevitable confusion.

Removed my node_modules directory and ran prepare-dev.py. Saw that everything
got installed correctly.
