Fix MaxTargetDistance == 0 not defaulting to unlimited range

Server config file has had a major overhaul (again). Overrides are now much easier to read and organise, and take up significantly less file space.

Existing configs will be automatically updated to the new format, you don't need to do anything 😃

WC armor definitions can now also have their resistance values modified by server config.
See wiki page for example configs.

Fixed NRE when stopping turret rotation sounds or some phantom spawns

Added check for PD targeting- should not try to shoot underwater if the fired projectiles will die hitting the water surface

Increased cooperative PD range check to the grid's MaxTargetingDistance, as defined by the longest ranged weapon on the grid (up from 3x the grid volume size)

Fixed some projectiles hanging in space indefinitely
