ash: A number of ui/ux changes from feedback/to better match the mocks.

The changes:
 * The network list scrolls on mouse-wheel.
 * The items in the network list cover the whole width of the list.
 * Increase the font-size of the date in the tray.
 * Adjust spacing between items in the tray.
 * Adjust padding in the user card.
 * Adjust the spacing and border around the shutdown etc. buttons in the user card.
 * Fix a crash from non-ascii username/email address.
