Loads schematics

- Jar contains default schematics which are copied to plugin folder (not
final, some are bad)
- Code now loads schematics and saves buffer schematics for faster load
(they are overwritten if schematic is newer)
- Some issues with schematic being used, chest wrong direction, torch
breaking... sign breaking... some schematic have lava and no floor...
some are missing their TNT.
- Moved some classes around
- Missing interpretation for jukebox noteblock, and some other container
objects.
