Save window layout into a "workspace".

The editor doesn't save window positions. I would be nice that the editor would save that information when you quit.

Ideally you would be able to save the window arrangement and be able to switch between them depending on what you are doing.

With [http://fife.trac.cvsdude.com/engine/changeset/3897 rev 3897], the editor in the cell_pathfinding branch has a prototype for achieving the requested functionality. The Plugin base class has some basic implementation, and the editor provides additional entry points to enable the plugins to save their docking status once it changes.

See LayerTool / MapFileHistory plugins for implementation details

(In [3907]) - added InstanceHighlighter plugin

• selected instances will now get a color overlay (can be switched to outline in the plugin code)
• removed instance highlighting from ObjectEdit plugin
  • added docking status saving to ToolBar widget class, added default docking settings for Toolbox
  • set name attribute for ToolBox to 'ToolBox' (was an empty string)
  • re-arranged init order in MainWindow.initGui() to make dockareas available for ToolBar
  • small change to screenshot icon to give it a bit more space on the left
