[TASK] The Number of The Workspace

This change ports EXT:workspace to Bootstrap and jQuery.

The workspace interface is simplified now, similar actions are tied together:
- The record history is now part of ``getRowDetails()`` to get rid of the extra
  button and popup.
- The "Send to stage" buttons are now also in the record information modal
  as separate buttons.

The JavaScript has some wrapper methods to simplify the remaining
ExtDirect calls.

ExtDirectServer::getDifferenceHandler() now instantiates the DiffUtility and
does not use the internal diff library directly anymore.
