Add dropdown for basic ammo types

[njfox]

This adds a dropdown to the item sheet to allow the user to specify the type of ammo that an item uses. It's only cosmetic now but ideally it would be tied to inventory later on for automated ammo tracking.

Only basic ammo types are implemented because I wasn't sure the best way to handle special ammo types, as they are supposed to have some restrictions (e.g. Expansive Ammunition is only allowed for Arrows, Bullets and Slugs) and I wasn't sure of the best way to validate that. Do you have any suggestions @Gerdofal ?

This is to address #38

The only other thing needed is a minor change to template.json to make it save

Would that look like this?

        "ammotype": {
          "value": "none"
        },

Close. Have to setup telco For a new employee. Will reply more later.

It would actually be a new property of the "weapon" template which starts at line 940 of template.json

"weapon": { "damage": { "value": "3d6" }, "ammo": { "min": 0, "max": 16, "value": 0 }, "weapontype": { "value": "pistol" }, "burst": { "value": false }, "fullauto": { "value": false }, "skill": { "value": "marksmanship" }, "rof": { "value": 1 } },

Gotcha, that's where I was planning to put that snippet, right below the ammo property. Just wasn't sure if I needed to add anything else
