Combat Robot Tweaks

[SleepyGemmy]

this PR tweaks the combat robot (i.e. syndicate cyborg/uplink borg).

changes

• renames "Syndicate Cyborg" to "Combat Robot" to better reflect its purpose.
• renames "Combat Robot" to "Military Robot" (the old code red/adminspawn one).
• removes the on-death explosion from the combat robot.
• tweaks the mounted netgun from 1 to 2 shots. reduces its recharge time slightly.
• tweaks the mounted submachinegun to do a bit more AP, so it is more usable against armoured opponents.
