Use logical cursor position and other minor changes.

* Remove unused member variable m_SizeVisu from base screen object.
* Move nearest grid position code into base screen object.
* Add get cursor position method to base screen object.
* Add position parameter to OnHotKey method in base draw frame and all
  derived objects.
* Pass logical position on left mouse button click and double click
  events instead of device position.
* Pass logical position to on right mouse button click instead of device
  position.
* Use logical event position parameter for locating items in EESchema
  instead of the stored position.
* Remove unused position parameter when displaying component edit dialog
  in EESchema.
* Comment out debugging macro in eeschema/template_field_names.cpp that was
  preventing debug builds using wxWidgets 2.8.x.
