New item system

Still apprehensive about jumping straight into all the complicated stuff of writing a new engine, I decided to start off with the item system. Basically, the item system now consists of two classes so far. There's the Item class which will be used to point to specific instances of an item (such as in a player's inventory) and will be able to contain instance specific data, such as quality, quantity, etc. The item class contains a pointer to a unique instance of ItemTemplate, which defines the actual item information of a given item type. So while there may be multiple instances of a PX45 Pistol, they'll all still get their base stats from the same ItemTemplate. This new system is different from the old one in that I'll now be able to add in various modifiers to specific items, which was impossible before.

In addition, I've made the ItemTemplates get all their data from a text file, which means anyone will be able to modify the game's items. The data file currently looks like this:

//TEMPLATES
//defines base characteristics for all items
item:base_template
{
    char:249
    cost:10
    description:"No description"
}
//defines gun characteristics
item:gun_template
{
    use:base_template
    char:191
    gun
    fireRate:1
}

//GUNS
item:light_pistol
{
    use:gun_template
    name:"PX45 Pistol"
    ammo:".45 ACP"
    damage:5
    magazine:10
}

It's pretty readable and offers a fair bit of flexibility. I think I like it.
