Archarodim:
	- Added automatic management of the 'Command Demon' Warlock's spell that can be used to cast 'Singe Magic' using 'Grimmoire of Sacrifice' on the Imp.
	- - Authorize custom spells' priority to be negative (down to -10) so that they can be used when a default ability is not available (until now the minimum value was 10). The slider still goes from 10 to 30 but one can type a value directly in the input box below the slider.
