Automatically ignore units

[sanguinariojoe]

It would be great to can add a list of units to become ignored by SpringBoard in the mutators. e.g. S44 flags, which shall not be saved to model.lua

Can be done (same for features). Would just need to figure out how that filter would look.
I think a function that receives a unitID and returns true/false would be best.

A couple of other configuration options would be useful. Something that filters which units are tracked for entering/leaving areas, so things like walls and buildings don't have to be tracked (with those whose unitDef has canMove~=true being the default). Similar thing could be used for those that we don't want to recreate every start/stop.

The previous paragraph isn't directly related to this issue, but it matters when thinking on how such an interface would look like (implementing the feature itself is trivial).
