Allow separate adjustment of grenades, ammo, health, and blocks

[lokka30]

Suggestion:

Allow grenades, ammo, health and blocks to be adjusted individually.

I would love to give players infinite ammo and blocks, but not grenades. This means that I either can't use refill or that I will use refill but make excess grenades 'duds'. I think it would be great if the protocol allowed for these values to be modified separately.
