[CMFM] bookmarks and history in a navigation drawer

* used a modified version of DrawerLayout from the Support Library
* moved bookmarks and history there -> always accessible
* added a drawer icon
* made all themeable
* removed the BookmarksActivity and HistoryActivity
* removed the BookmarksAdapter and HistoryAdapter as they are useless
  for LinearLayouts. I couldn't use ListViews because they scroll
  vertically - as well as the drawer itself.
* removed the layouts for bookmarks and history
