[Suggestion] Navbot capture on Special Delivery and Player Destruction

[explowz]

Make navbot be able to capture on Special Delivery maps sd_doomsday and sd_doomsday_event and Player Destruction maps Cursed Cove (pd_cursed_cove_event), Farmageddon (pd_farmageddon), Monster Bash (pd_monster_bash), Pit of Death (pd_pit_of_death_event), SnowVille (pd_snowville_event) and Watergate (pd_watergate). The bots should need to be able to pick up the australium, and once they have it walk to the rocket platform (or in case of the Halloween version the strongmann) and stay there until it gets captured. Same for Player Destruction. They should pick up those pickups and when they have enough (or a max limit. Dunno, never played the pd maps myself) they should drop them off at the map's drop off zone.
