Lots of ui-improvements.

Added the ability to remove combatants from the combatants list, added the ability to remove zones from the zones list, fixed some bootstrap formatting, and cleaned up a lot of lingering ui issues.
Updated to latest font-awesome and bootstrap

fontawesome (for new icons), and latest bootstrap for using an old css with
a new javascript.)
changed the style for the main page, to avoid issues on smaller screens. Also, filter out mpas you own from maps you participate in.
