Add new triage tag mechanics

[Estutes]

In my opinion, triage tags are awesome but rarely used, and I think they could be even more useful.

Sometimes seconds count, and you are working against the clock/ticks before the other pawn dies in a sort of click and drag speedrun. This prevents you from calling other people to help you when needed, which would involve a lengthy explanation of what's going on. It could be fixed with code levels like hospitals do, but would add another level of complexity that may be unnecesary in an already somewhat complex area of the game for new players.

I think a good way to mix these two together is to add a notification in the chatbox. And also add a new triage card that wouldn't actually change the patient triage color, but it would prompt other medical players to move towards the patient.

As for what information should be received as the notification, black and green should be normal size text. For yellow, the notification should be a big warning with information related to the patient. For red it should be a massive emergency with (I think) a snapshot of their suit sensors (if they got them on). Lastly for the ping: a big pop up for the player receiving the ping notifying thme XYZ medical doctor needs all hands in certain place. This would also work for those patients that have been on red tag for a while but suddendly need all hands there again. This distinction would allow players to distinguish between:

1. Clear information about a present issue that may/may not act on. They have room to decide wether to respond or not.
2. A clear call for help from another medical employee. The receiving end is actively pressed to answer.

A slight variation of the ping idea is: Instead of a new triage card, it could be a small variation of the ringers tweaked for medical. This could be more neat but less useful for players.

And for the delivery method, I have been thinking for a long time and I am not sure how. There are a ton of options that seem equally valid at a first glance: doubling the medical analyzer as a notification board. Creating a new PDA program, adding a new drag medicHUD to PDA, making it a context menu on/off on the medicHUD... As for the ping, same thing, it could be all of them or some other variation depending if we decide it's best to use a variation of the initial idea.

This new additions could be cheesed against antags, which may or may not be fine, but countermeasures could be added such as adding noises, /me actions in the chatbox, cooldowns or it being limited to being in certain place (medical bay only for example) and be certain equipment only. This would make people think twice before using it against an antag (they still can just ;help so...)

I think this is a good idea but there is room for improvement to refine it. This is just an idea and ways that it could be implemented. Plus this suggestion is already long. I have plenty to say but I'm tired of writing lol.
