Title: Don't lose focus of the 1st pane if it's empty

At the moment, if you tab when the 1st pane is empty you can start searching for objects in QS's second pane which is just plain weird and can cause QS to crash. This commit only lets you leave the 1st pane if it has an object selected.

This is something I fixed about 2 years ago, but never released as I has some 'fancy' ideas that if you tabbed from the 1st pane when it was empty, QS would try and pull the current selection before resigning first responder.
I thought it was kinda cool, but not really worth it. [Here's](http://d.pr/n/xXnL) the code snippet if anybody's interested
