Invisible 1.0

This plugin adds craftable item frames for survival. Just put eight item frames around an ink sak and there you have it. These Item Frames are visible until you place an item in them, after that they will stay invisible until the item is taken out which triggers the item frame to turn visible again.
Note: This is one of my first public projects, feel free to give me constructive feedback.
