Add hunger and thirst (#363)

* Add hunger and thirst

Based on the SS13 systems.
Food (Nutriment) / Drink -> Stomach -> Hunger / Thirst

* Cleanup rebase

* Cleanup stuff that was prototyped

* Address feedback

Still need to add a statuseffects system in a separate branch

* More cleanup on nutrition

Fix Remie's feedback and also damage tick.

* Re-implement nutrition with master

* Updated to use the StatusEffectsUI update
* Removed all clientside components as they only receive the UI updates now
* Implemented PR feedback
* Had to make a slight adjustment to the chemistry SolutionComponent given it doesn't have an Owner, same with Solution

Still TODO:
* Metabolisation effects
* Change drink contents to alcohol / wine etc.
* Add items to the dispensers
* For transparent containers use RecalculateColor

Could probably genericise DrinkFoodContainer as well to be a temporary item dispenser

* Fix broken bottle parent
