Remove Flahers and Riot Launchers

[BaneOfGiygas]

I'm fine with the smoke grenades from riot launchers being annoying as hell, that's fine. But when the thing has just about no other purpose beyond devastatingly niche and/or situational uses, I really wonder why it needs to be there and why it's presented as a tool available to security when about 80% of the people using it aren't security. It's less a thing security is able to use and more a thing that security has to make sure people don't misuse, and that strikes me as shoddy design.

As a result of this, I fully support the idea of alternate ammo types, as this gives security reason to use them during their normal security-ing.
