Results table and section frame overlap

[dyollluap]

2.1.x testing:

When looking at results on a smaller window (e.g. laptop width), the results table overlaps with the page section frame that surrounds the facets and results table. Consequently every other row in the results table has the frame line appearing through the middle of the field. Visible on Safari, Firefox and Chrome current versions.
Attached is a screen capture of the problem:

This was actually a positive design choice at one point: rather than having the whole frame slide off the right, the table indicates that the window (or zoom) needs to change to be contained--behaviour from A1.x, where bugs were reported for the converse issue.

However, this will likely all become moot with moving everything over to bootstrap in #104; we'll be farming out styles and table handling to that system instead of having our own. This will also give us a chance to look at table compaction, etc.
