- Changes to old permission names
- every modifier has its own permissions now (for applying, crafting (only through bookshelf), using (not vanilla enchantments))
- permissions for elevator and builderswands
- permissions for crafting, upgrading and repairing a MineTinker-Tool

Tweaks:
- Auto-Smelt has now a random Luck-Integration (as requested by TheLegendCookie)
- Power has now a MaxLevel-config option (Have fun with Power 100 [199x199 Blocks]) (as requested by TheLegendCookie)

Fixes
- fixed NullPointerException mentioned by Olivo and EpicnessTwo [ #11]

Increased version number from a6.1 to a6.2

(as a little side-note: I am taking a break for a few weeks; expect the next update at the earliest in mid September)
