EESchema command handling and other minor improvements.

* Schematic editor cancel current tool command now use a single command
  ID that is used everywhere the event is generated.
* Moved cancel current tool code from Process_Special_Functions to a
  separate event handler.
* Add idle check method to block select object.
* Add block active check to base screen object.
