Allow tasks to be subprioritized by drag-and-drop Summary: Like the title says, similar to Facebook Tasks. Not sure how I really feel about this, but I guess it's kind of OK? I never used this feature in Facebook Tasks but I think some people like it. The drag-and-drop to repri across priorities feels okayish. Because subpriority is a double and we just split the difference when reprioritizing, you lose ~a bit of precision every time you repri two tasks against each other and so you can break it by swapping the priorities of two tasks ~50 times. This case is pretty silly and pathological. We can add some code to deal with this at some point if necessary. I think this also fixes the whacky task layout widths once and for all. (There are a couple of minor UI glitches like headers not vanishing and header counts not updating that I'm not fixing because I am lazy.) Test Plan: Dragged and dropped tasks around.
