Battlegroup boats

[FatRefrigerator]

Q	A
Bug fix?	no
New feature?	yes
Needs wipe?	not technically

Description:

Adds boats as part of the battlegroup spawning logic.
Boats will spawn from markers placed in Eden similarly to the airspawn markers.
Boats will navigate to player-owned sectors near water and loiter in the area.

Content:

• Boat spawn script
• default (custom.sqf) opfor preset has the boat array added to it
• Any maps will have to be updated with the empty markers labelled "opfor_boatspawn"

Successfully tested on:

• Local MP
• Dedicated MP, not this version specifically, but it work on 0.96.7 and all I did was update variables to the 0.96.8 standard
