Add a Chat Notification about abilities in Zombies

Add a chat Notification about abilities in Zombies Gamemode

When new players join the game, all to often they have no idea that abilities exist. My suggestion is for a chat pop-up, kind of like the one for map voting, to appear in chat when joining the game.

My Suggestion for the Message:
This GameMode has abilities!
To view these abilities, use /abilityhelp to view a list of abilities and /abilityhelp (ability name) to view information on the ability.
To select an ability for use, use /ability (ability name)

Possible Objections to this Suggestion:
I actually can’t really think of any, so I guess write your objections in the replies and I’ll respond to them as soon as I can.
