[MAP] Adds Syndicate Borgs

Nuclear Operatives can now order a Syndicate Borg for 25TC. After
spawned, a candidate from ghosts is chosen to control it.
It has a 25k cell and the following modules:
-Emag
-Esword
-Ebow
-Laser Rifle
-Jetpack

All weapons use 100 charge per shot.

2 borg rechargers have been added to the Syndicate Shuttle for the
Syndieborgs to use.
Changelog will be added in a separate commit.

Comments related to balancing are welcome (also in the forum thread when I make it, hopefully very soon).
