Facia tool modules - refactor

There are two commits for an easier code review, one is simply updating bower.json and dependencies.

The rest is adding the possibility to change layout in the fronts tool and decide how many columns to display. It's also possible to chose the column's type, however `ophan` and `external`are behind a switch (drag and drop doesn't work for security reasons).

Apart from that, few minor layout changes and lots of new bugs :grin:
