[MERGED PR] Removes the security alert HUD button

[Katzen]

I'm not a huge fan of this, if you have to open up the pda to use the alert experienced players will just leave the pda open all the time. This mostly nerfs newer players but does nothing for experienced players. It also removes the convivence of sending an alert, meaning stuff like pretyping radio messages/pda messages become as convinent as security alerts, and the former doesn't alert the antagonist nearly as much about the incoming security swarm

This is my main thought, I used to do this on classic sec because of how fast you'd get jumped. However, I don't see what you can do about mechanical optimizations going to the extent of pretyping messages. That's a playstyle and attitude issue you can't really fix by code.

My take is that security should be reliant on the radio. I think the pager might be the acceptable comprimise that works for both servers but I'm not sure it changes anything about the "security death ball" concept.
