DB Less, Knockout Sortable, Latest Bootstrap

* FIX: Add the trashcan back. Trashcan hover effect. Show trashcan when
drag & drop starts.
* FIX: After drag & drop, news tile would get duplicated after page
reload.
* CHANGE: Remove tile over underline text.
* FIX: Tile sort bugs fixed by using the knockout.sortable plugin. My
custom implementation of sortable was buggy.

closer to ASP.NET free implementation.
* ADD: Updated jQuery and Bootstrap. So many breaking changes!
