Convert individual tabs to bootstrap grid

[ddrury]

Replaced the containing table with a bootstrap grid. This fixes all the problems with content overflowing the right margin and even looks reasonable when the browser width is reduced such that the columns fold.

Requires two new webtrees classes for theming, everthing else is pure bootstrap.
