CF: Casting time & spellcasting monsters

[Samuli Tursas <samuli@voimax.voima.jkl.fi>]

Hi there.

Casting time is actually an upgrade for players. Spellcasting monsters 
don't cast spells as often they used to cast without CASTING_TIME defined.
Also monsters lose their spells when player hits them, which sure is an 
upgrade for fighters.

It'd great to have a CASTING_TIME which wouldn't affect monsters at all, 
casting time would only affect players. (The game needs downgrade for 
spellcasters)
