Reimplement decay, recovery, and allow decay from captured state on control points

[lefckntea]

make it so capture points have those

[Pablete1234]

1.9+ PGM had decay and recovery attributes added, which handled how quick points uncaptured or re-captured, replacing incremental (which simply resets progress to 0% if set to false, or doesn't change progress at all if set to true), additionally, it'd be nice to have a new flag for a point uncapturing on its own (if no one is standing on it) which was the original feature-request when decay & recovery were implemented, but got lost in the way

*Also a way to have decay from captured state but not decay from an uncaptured state. So your progress while capturing a point stays but it can then automatically uncapture from the capture state

[Pablete1234]

Then the proposal would be decay, recovery and owned-decay, which defaults to infinity.
decay applies when it's not owned and partially captured and no one stands on it (or only non-capturing competitors are on it)
recovery applies when it's owned and partially uncaptured, but the capturers all left (eg: no one on it anymore)
owned-decay applies when it's owned, and owning competitor isn't on it.

recovery and owned-decay are mutually exclusive as one is ticking up and the other ticking down, while owned
