Made bin view horizontally scrollable

Fixes this http://d.pr/i/IfSI

Fixes the fact that you have a 30% (sometimes 250px) sidebar overlapping the code. It also fixes insane line wrapping.

One could argue that you should instead make your sidebar position: absolute; so it isn't overlapping, but that wouldn't fix the line wrapping and would take more rewriting.
