Allow sec tokens to be bought from the vendor

[Drago156]

The whole point of the security vendor was to prevent it being easy to steal all the sec equipment and limit the amount of sec equipment in a round.

Hear me out: maybe the round should have some basic security gear to start? *because I have personally witnessed 40+ pop rounds with zero sec*

Qm can buy tokens.

you still need a sec ID, explosives, packet nerdery, or EMAG to open it
