12/17/15 - NOTE: A re-work in the process. A working version is currently privately available and is waiting on public release. Please note that, on the outside, it will be less dynamic than the current version and quite a bit buggier. Unfortunately, this does tend to happen with code re-writes. Please stay tuned as the project is turned over to BETA and updates will be released accordingly. More to come this following week...
12/29/15 The re-work is near completion! Expect a release on New Years' Eve
1/1/2016: Happy New Years! Enjoy the update.

Lootboxes, mystery crates, loot chests, loot boxes, loot crates, whatever you call them! Reward your players for finding them & their keys (configurable) for epic loot!
Lootbox is like opening a chest, but it's in your inventory! You can configure it so that you can have multiple lootboxes that may or may not require keys to open. When they are opened, they can execute commands from the console and/or give items to the player. This will probably be the best drop party gift you could give your players or one of the most desired quest items! The possibilities are endless!
Lootboxes are, by default, chests with a special name and lore. They can be opened either by themselves or by a key (tripwire hook) as determined by the config.yml. They can be used in the following and more: Quests, treasure chests, drop party items, trade, donations! But really, the possibilities are endless.

The chat options should be self explanatory.
Make sure that players have enough room are online and have room in their inventory when using the /lootbox give command. If they aren't online it won't be given to them and if their inventory is full it will drop at their feet, prime time for others to steal it.
