[MISSION] Yiresa - Black East

Got around to updating this after a long hiatus, I can't be bothered to list every change so i'll just mention what's important okay sorry

Notable Changes that aren't exactly wave exclusive :
- Sentry busters have a hat now.
- Any tanks that spawn after the gate has been capped will gain a speedboost, moving them faster to the gate. A sound cue will play if this happens.
(though sometimes it just plays after the wave ends??? I think that's a spectator thing.)


Wave 2 :
- Reworked subwave #2, it is now entierly punchie city.

Wave 4 :
- Fixed the last subwave having a waitforallspawned so gatebots shouldn't be screwing up diffculty anymore.

Wave 5 :
- Giant Cowmanglers now have a maxactive of 6, yippie.

Wave 6 :
- Refer to lastest judge feedback.

Wave 7 :
- Some limited support has been added before the standard support kicks in.
- Chief HOK himself has been added.
