Magical weapons

• Charging the Hammer of Notch is now much less awkward, as it now takes away the XP points instead of percentage towards next level, and it can eat through a whole level too.
• Re-added the jetpack, with many changes (you now use the SHIFT key to propel yourself!).
• Lightning ball spell will now drain mana of all the players in it's area of effect.
• Small changes to the commands (you can now specify what kind of tnt sword you want).

This is only a pre-release so you guys know that I'm not dead :P . I will re-add the items from previous versions, but I plan to redesign most of them. Also a lot of new cool ones are comming!

• Flying with jetpack for too long can result to player getting kicked, if you have allow-flight set to false.
• Jetpack permissions are not defined in plugin.yml. They might work, but probably need to be added in addition to the .* permissions.
