Spell effect predicate logic.

At present, there seems to be a single field for each spell to have a secondary effect. I'm not sure if you can chain these together ot have more than two effects for a spell or not (Unfrozen seems to indicate yes,) but you should be able to do so.

Spells should instead have *six* secondary effect fields.
Secondary-effect-each-effect - EACH effect generated by this spell also gives this spell if that effect returns TRUE, hitting/centered on that target (if applicable).
Secondary-effect-once - The spell also generates this effect. This is equivalent to the current secondary effect field.
If-TRUE-secondary-effect-each-effect - IF the predicate of the spell returns TRUE for any given target, generate this effect on that target.
If-FALSE-secondary-effect-all-targets - IF the predicate of the spell returns FALSE for any given target, generate this effect on that target.
If-TRUE-secondary-effect-once ; If-FALSE-secondary-effect-once - likewise, but

Spells with magic resistance return TRUE if the magic resistance fails, and FALSE if it succeeds, on a target-by-target basis.

Otherwise, most spells just return TRUE.

However, we'd have new effects which all they do is check predicates. There'd be an effect to check for the presence of magic paths, an effect to check the size, etc. etc. Most of them would take bitmasks in the damage value.

With this, we could make a spell which, if it targets an earth mage, tries to kill him, and if he fails his magic resistance check, summons an earth elemental in his square, for example. You could do all kinds of interesting and complicated stuff.
