Lighter Mod

- Lighters are now added by creating a new instance of the 'ItemLighterOpen' class instead of extending it. (This removes the need for individual classes for each lighter.)

- Boxes are now added by creating a new instance of the 'ItemLighterBoxed' class instead of extending it. (Same reason as with the lighters.)

- Modified the right click event for boxed lighters to remove the need for a box content variable. (Also to remove the need for individual classes, adding new lighters is so much easier now.)

- Lighters and boxes will now both have their model name prefixed with 'Model: '
