Add a GetTextSize() method to GUI objects

Browse Source 
Usage:
  let size = Engine.GetGUIObjectByName({gui_object_name}).GetTextSize()

Returns a JS object containing the height and width of the primary text
field within
the object, taking into account new lines, text wrapping, and font
changes.

Unless the object doesn't contain text, in which case the method will
return undefined.
