Intercontinental Gaslighting (#998)

* diversified building management by injecting behavior; allocated entries for the intercontinental lattice and have begun connecting warp gate entities along the intercontinental lattice; beginnings of warp gate broadcast operations; disabled free merit commendations

* allow transit across a predetermined warp gate path, i.e., proper zone-to-zone gating

* game variables for modifying warp gate behaviors; moved choice of building game logic into overloaded constructor; only handle the capitol fore dome in more realistic conditions; warp gate state restored primarily b y internal game logic; changes to which and how gates are declared inactive or broadcast at startup

* initial work on WarpgateLinkOverrideMessage, even if the packet doesn't seem to do anything; added basic service for rotating cavern zone locks via the galaxy messaging service; moved error checking for lattice connectedness

* cavern closing warning messages queued

* starting to set up ChatActor for /zlock command, and added /setbaseresources; conditions for correcting broadcast conditions of a locking warp gate pair; system for rotating through locking and unlocking cavern zones only uses two timers now and has an advance command that speeds to the next closing warning or cavern opening

* expedited cavern rotations available via '/zonerotate' and '!zonerotate [-list]'; '/zonelock' should work for caverns, though distorting the rotation order to accommodate the cavern being unlocked; configuration arguments exist for the setup of cavern rotations and for the rotation itself

* populated cavern lattice connections for a specific rotation order; warp gates will properly activate and deactivate and modify their neighborhood information based on which stage of the rotation; fed up with the blockmap going wrong; added a sanity test for the cavern lattice; Spiker damage calculation changes

* adjusted local variable requirements of BuildingActor to integrate retained actors more closely with the Behavior; on the other hand, another value is passed around the logic

* bug fixes observed from issues found in logs since 20220520; halved the spawn height when gating to a cavern warpgate

* cavern benefits are now represented by enumeration classes rather than additive binary numbers; when facilities change state, benefits are evaluated; when caverns rotate, benefits are evaluated; cavern facility logic added; attempted handling for inventory disarray conditions (untested)

* broke down tabs for easier navigation; added test to stop spawning of cavern equipment when not otherwise permitted

* code comments, everywhere; correcting issues with cavern rotation timing reports

* but is it flying?

+  * A service that assists routine access to a series of game zones

+  * <br>
+  * The caverns were a group of game zones that were intended to be situated underground.
+  * Access to the caverns was only sometimes possible
+  * through the use of special above-ground warp gates called geowarps (geowarp gates)
+  * and those geowarps were not always functional.
+  * Usually, two caverns were available at a time and connections to these caverns were fixed
+  * to specific active geowarp gates.
+  * The changing availability of the caverns through the change of geowarp gate activity
+  * was colloquially referred to as a "rotation" since it followed a predictable cycle.
+  * The cycle was not just one of time but one of route
+  * as one specific geowarp gates would open to the same destination cavern.<br>
+  * <br>
+  * The client controls warp gate destinations.
+  * The server can only confirm those destinations.
+  * The connectivity of a geowarp gate to a cavern warp gate had to have been determined
+  * by opening the cavern with an appropriate packet
+  * and checking the map description of the cavern gates.
+  * The description text explains which of the geowarp gates in whichever zone has been connected; and,
+  * where usually static and inanimate, that geowarp gate will bubble online and begin to rotate
+  * and have a complementary destination map description.
+  * Opening different combinations of caverns changes the destination these warp gate pairs will connect
+  * and not always being connected at all.
+  * The warp gate pairs for the cavern connections must be re-evaluated for each combination and with each rotation
+  * and all relevant pairings must be defined in advance.
