Divided the purchasable food items into different groups.

Previously when you right-click on a plastic bag or money itself, you get a very long list of food that you can buy. I always found it very tedious scrolling thru almost over hundred of items.

Now they are divided into groups like: Meat, Vegetables, Fruits, Dairy Products, Sweets, etc...

Once you purchased the first item in that category, you can spend additional money to gain access to the rest of the category.

Some tweaks

Increased meat harvesting time.

Among some other things:

- Reduced the types of meat harvested from zombies down to just Steak, but now we won't lose the tool.
- Axe / Wood Axe / Hand Axe / Machete / Katana added to tools that can be used to harvest meat.
