(1/2) Lockscreen calendar now supports all-day events, event description and location, new calendar icon

* Lockscreen calendar now displays all-day events in correct timezone.
* All-day events display as localized "Thu Jul 4" instead of "Thu 5:00 PM" (date instead of time).
* Added event location and event description on newlines underneath title, if either are set.
  (Can toggle display by: Don't show; Show first line; Show all)
* Use calendar icon instead of alarm icon for calendar, and alarm icon for regular alarms.
* Adjusted lockscreen layout so widgets fit better:
  moved "now playing" to directly above music controls in portrait mode
  moved music controls to bottom left corner in landscape mode
  moved album art and "now playing" to right of music controls in landscape mode
  "now playing" text appears over tabs/rotary/rings widgets instead of behind
  album art resized smaller in landscape mode
* Music "Now playing" widget now appears correctly in landscape and portrait modes
