[MERGED PR] makes pressing the security alert/crisis alert give a chatbox notice, ...

Looks good. 

I do think the text font should be different, perhaps something like the silicon chat font, so people are clear that it isn't you talking. 

The alert text should appear in chat log, something like:
*Emergency alert sent*

I think dropping "Please assist this officer" will avoid later issues. Such as new players unintentionally assisting traitors. 
And, very pedantically, not everyone who can send an alert is an "officer".

You might also consider making versions for medical/engineering/janitorial emergency alerts (if you would like further work lol)
