From 92fc64655c5b51ddec3286befd87d9693ca718c2 Mon Sep 17 00:00:00 2001

Subject: Update to use bundler and work on Ubuntu Trusty.

Switching to bundler saves confusion about gem paths when running
sass/compass to compile the CSS.

Trusty can use precisely the same packages as precise, with a few tweaks
to generalise the contents.
