Add AMMO REMAINING value to combat screen

[lotusware]

Players will have to rely on the DM or look at their inventory for ammo management. There is room in the combat screen for the weapon to check for ammo and return how much is left.

Added a value in app-data that appends to the equipped weapon description.

It has three states:

• No ammo required (appears blank)
• Ammo required and available
• Ammo required and not available
