0.6.0

• First attempt at writing out 'proper' ground effect IDs.
• Move metadata files to meta folder.
• Decrease chances of IO conflicts while saving maps in Noggit in convert-on-save mode.
• Fix crash during ADT generation if flags weren't set properly.
• Only regenerate groundeffects when they are not set through Noggit.

Still not recommended to use, if you do make sure to have backups of all relates maps/files and don't expect any support.
