Create revive/respawn command(s)

[VulpusMaximus]

This is a basic thing, but will be more than just respawning the player. At least one older version of this addon included this, and to my memory had respawn and revive be separate commands, with the revive command resetting the target entirely and respawning them as if they spawned normally at the start of the round, and the respawn command just respawning them where they were, as they were, when they died.

These were separated both because of how the gamemode deals with spawning/dying in a round, and because different situations may call for either one of these options on a server. Ideally, I'd like to keep these separate commands if my memory is correct and JB7 does work the way I remember.
