Map effects can update once per game turn instead of once per base turn; all following map effects now use this for more precision

Unstoppable is not classified as an "other" effect, making it unaffected by Timeless and its cooldown can not be reduced either

This lets talents / effects add themselves to lists at appropriate
times. Bascially, just a quicker way than searching for all applied
talents/effects for a specific tag.

Talents can have a sustain_lists and a learn_lists field.
Effects just have a lists field.

Example:
talent A has the following:
learn_lists = {'red', {'blue', 'green'}}
When you learn it, your character now has the following fields:
self.red = {'T_A'}
self.blue.green = {'T_A'}

Modified stealth and step up to use this system. So, to make something
break when step up does, just add it to the 'break_with_step_up' list.
