ArsenalsInit: Initialise arsenals (markers/trashcan init) during server init

[dijksterhuis]

Was writing up the wiki and felt very weird having a dance between having N arsenal_cleanup_n trash cans, where N must match the index of the arsenal (what if someone wants to put down two trash cans for one arsenal?!).

This adds some server side initialisation logic to make life simpler

• Finds the white listed arsenal module logics
• Any object synchronised to the logic is considered an 'arsenal'
• Add pink map markers for all arsenals
• Save arsenals missionNamespace setVariable ["vn_mf_arsenals", _arsenals]

When a player joins, we can just load trash cans by finding relevant objects within 10m of the init'd arsenals instead of having to find different map markers and resolve the trashcans based on indexes of map markers.

TODO

• Remove arsenal markers from each map (will be automatically created on server init)
