Adds the M540-B Armored Recon Carrier to the game.

The M540 is meant to act as a mobile command & intelligence post for deploying CIC officers, with all the equipment they'd need (see design doc for list). It can only be driven by SOs, XOs, COs, and synthetics.

The M540 can be obtained for 5 intel points at tier 1. Numbers subject to change.

The primary features of the ARC are the RE700 rotary cannon sentry and the U-56 radar antenna. The U-56 takes 8 seconds to retract or deploy. When deployed, the ARC is anchored in place but has a radar function akin to the command APC. Since the ARC is now a sitting duck, the RE700 rotary cannon is activated. Any non-USCM personnel or life forms that come within 5 tiles of the ARC will be fired upon automatically.

Explain why it's good for the game

Deploying command personnel can be hard-pressed to stay alive or relevant at times (without just becoming a pointman [COs] or medic+ [SOs]). The ARC gives groundside command personnel the ability to coordinate and lead from safety, in addition to giving IOs a potential dropoff point to upload intel and decrypt disks.

Todo

• Get side-facing movement sprites for the ARC
• Get a techweb sprite for the ARC

• arc sentry now shoots out to 5 tiles
• arc is a bit more fragile
• fixed an assortment of bugs

Should revisit using damaged_hardpoint and damaged_antenna as the damage overlay rather than color changes; but its acceptable enough for now.
