Revolution Improvements (#7878)

- Added a new category to the traitor uplink, which is only available to revolutionaries.

- Head Revolutionaries now spawn with an uplink that has 50 TC, they also get an alert telling them to not abuse it.

- Revamped the drill dropper into a generic orbital dropper, capable of dropping ANY sort of item you wish it to.

- Added a Mech orbital dropper. Added an Armory orbital dropper.

- Made loyalty implants display their text correctly when they implant someone.

- Added aggression implants, which makes whoever it is implanted into extremely aggressive. Quite useful for starting a revolution.

- Added some description_antag to mercenary cipherkeys, informing the reader that the mercenary radio key is :t.

- Added a gear crate (not for mercs) which is just six syndicate softsuits. Useful in a pinch.
