feat: handle the 'pivot' parameter of the Geometry Applet

Browse source 
Dealing with general click and drag on the applet and differentiating
  between a background drag and dragging an element seemed like too big
  a task, so this PR simply provides a slider to rotate the diagram when
  the pivot is defined.

  Implementing this required storing much more construction data, and
  also dealing head-on with GeoGebra's shall we say "strange" choice where
  the value of an expression depends on what name it is assigned to...
  The resolution of this last bit was to use different GeoGebra names for
  Geometry Applet points that start with something other than an uppercase
  Roman letter.
