[CLOSED PR] Removes crit alert from health implants

[Dhaidburt]

I think that notifying of crit is the biggest part of using a health implant in the first place. If you're already scanned in, what's the point of a health implant other than having medbay/sec bring your stuff back to your freshly cloned body? It also lets medbay get outa their little playpen and really let em know when shit's hitting the fan if there's multiple alerts back to back.

Also yada yada puritan likes them yadda yadda
