Added Hunger System

Needs more work, but progress bar works, displaying the hunger level.
And when a players hunger level reaches 0 their health begins to drop.
All these settings require tweaking, timings set up properly. And more
features added such as over-eating, health going up when hunger bar is
over 85% and more.
Also I plan to add an eating animation.
Upgraded hunger, and inventory (weapons/food)

I've upgraded the hunger system, but it still needs work.
I've also added functional food to the inventory system, upon using the
food out of the inventory the player broadcasts to local players that
they are eating (like an automated /me command) and informs them that
their hunger has gone up.
I've also added weapons in a similar way, but the weapons don't get used
up upon use, this allows players to go back into their inventory and
place their active gun back in it's holster or take out another gun.
Still needs work but functions nicely so far.
