Nerf/Tone down security somewhat

[Ikea]

Its a lot easier to tell new players to put disk on a table then to tell them to head to medbay and get clone scanned. Not to mention, due to there position security officers are both more important to have in a round, and are especially vulnerable to being gibbed. Most of the time when I find myself using the disks its to bring a newer officer back into the game who wandered into space or to bring some security officers back into the game after they were chilling in security then a ttv came flying in through the mail chute.
