Convert tab table to bootstrap grid

[ddrury]

Proof of concept - Do not use for production

This only works on the webtrees theme for the Individual facts and events tab, (other things will break!!!)

I think this is suitable for production now

I've 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.

It only requires two new webtrees classes, primarily for theming, everthing else is pure bootstrap.

I'd appreciate comments particularly on whether it's worth continuing down this path

BTW I've included a fix for https://github.com/fisharebest/webtrees/issues/4853
