Re-work the layout computation for MessageListItem
This now uses an XML layout that gets inflated and computed after a layout pass. The drawing simply uses the coordinates stored after the layout. This makes it a lot easier to maintain the different views and allows us to simply provide different XML files for different modes/views, isntead of trying to hand tweak Java layout code. Some TODOs - clean up the "paints" and optimize the layout/drawing computation Change-Id: I784919f726bd4d80aba8744a8f047fcfe79ad93a
