Proximity Terminal Fix (#241)
* modifications to ProximityUnit and related classes to internalize the effect control for the terminal, removing the flywheel functiuonality from WSA

* proximity operations for medical terminals (the one in the Anguta lobby, specifically) is functional; some entities besides Player now keep track of the continent they possess, a necessary compromise for proximity ops

* repair rearm silos (Anguta courtyard East) demonstrate operational behavior when lattice benefits are active

* proximity terminals may now juggle multiple targets that move in and out of range and change validity over time

* previous rebase; preparing for special location + offset calculations for utilities

* working location-based proximity repair terminals for the lodestar, utilizing new fields in the vehicle definition, new configuration method in the utilities, and new calculations for Vector3 entities; some comments and tests

* separated ProximityTarget; updated existing terminals; restored defaults; preparing to fix tests

* tests involving the proximity unit workflow

* dismantling a portion of the proximity terminal machinery that is no longer necessary and only poses risk to the system; removing temporary code used to quickly test vehicle silo repairs
