Bootstrap skin

I started to fix bugs in the flat skin and decided to start over... ish.

Reusing most of the existing ZM framework - just changing client side to look better and be easier to maintain.  That means using bootstrap for css.

This PR is not ready to merge, but I would like feedback as I go through and make my changes.  This PR should however work fine if it were merged - it just isn't complete.
