fix(client): add "Referer" header to requests

When running Deis behind an SSL-terminated endpoint, there are
issues with Django's CSRF protection. Adding a Referer header
is mandatory when using SSL with Django.

Reference: https://code.djangoproject.com/ticket/16870

fix(Makefile): fix component rsync

Currently, trying to issue a `make -C <component> build` will rsync

of /home/core/share/<component>.

This commit makes all rsync commands rsync relative to the root directory
(using the path to includes.mk as a reference).
