Action menu added to the top of UI

Action menu includes the option to reflect Guide Markers. This might get
upgraded to reflect any type of control or item in the RigGraphicsView.

The "Clear All" option was also added top the menu with a separator. This
has allows the user to clear the RigGraphicsView from the action menu. In
the clear() method a query input has been added, so the user is presented
with a messagebox, when they try and clear in this way.
Control Options DockWidget is now removed

This dockwidget has now been removed since all the options are now
accessible in a much neater form from the 'actions' menu and the top too
bar.
Filter Option Tool bar renamed to Quick Tools

Rename has occured since the tool bar has filled up with much more
generally useful tools. Space has also been added to the start of the
toolbar using a Qlabel widget with just a load of spaces as the name. This
is just make start point of the tool bar line up to a more athestically
pleasing place.
