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.

New Actor:addParticles3D to automatically handle particles with "noup"

Removal is done by rewinding an object and replaying all other egos on
top of it. Not too fancy, but surefire.

It required some minor additions to the engine code, but nothing too brutal.
instant_resolve = "last" now runs last resolvers as well;
generic and genericlast resolvers now receive additional arguments
that are passed to resolvers.
