0.3.x ui changes

Added an "All" tab for requests: http://i.imgur.com/0DNIGDp.png

Let me know if you have any comments about the columns I put in for the table.

Also updated the request state box in the request detail view: http://i.imgur.com/1bGJ2to.png

I considered a bunch of places to put in but since that text area is context-dependent and changes with the state I figured that's the best spot.
