More redesigns + annoying bug fixed

I did it once again. I redesigned the inventory categories for weapons and equipment. Now the screens are easier to use and look much better.

The new weapons screen

Now it is not possible to change the equiped weapon via the inventory screen.  The weapon inventory is now only for showing your arsenal of guns and the amount of ammo you are carrying.

The new equipment screen

Te equipment screen has moved from horizontal pattern into a vertical one and is now more like the other inventory screens. It also shows more information about the armors you have.
