Recents modifications [DO NOT MERGE.......EVER]

- Changed layout from linear to grid
- Added another column
- Adjusted the app icon/label and callout line

This was more or less something that I took as a challenge while talking to
Sean Hoyt and because is fucking saturday and there was nothing to do lol

The recents clear all drawables overlay the recents and is just not ideal at all.

Highly recomment if someone does pick this, they should adjust the columns to maybe 1 and
resize the thumbnail to maybe get a PA recents effect or WebOS....

***AGAIN, THIS IS DOES NOT GET MERGED INTO DIRTY UNICORNS.........EVER!!!***
