minor code clean up in ArticleList::onItemSwipe
Added support for marking aritcles read and unread, including modifying the CAB icon to reflect the current action mode
Added stub call to prompt for 'undo mark read' for a multi-item mark unread
General fixes related to article elements not being shown when they should be and also some work done on migrating the mark articles read/unread to an asynctask
Fixed a bug where marking all to be read/unread didnt actually make every article read or unread
re-commiting after a while away, just to start fresh
Fixed multiselect mode bug that would cause CAB to exit when items were still selected
