Resizing finally fixed? - minor style update

Looks like we did it - sidepanel handling now bypasses Foundations grid. Looks much more resistant that way, I think we finally did it and can now say that the sidepanel is really working.

What we still want: Min and max boundaries maybe, but we can add that later.

Starts with restyling the tab pills a bit. We'll see where we want to go with it.
