Version 0.6 release.

 * Changes the way item keys work.  No longer
   contains the texture in the key.
 * Added a migration to convert old keys to the new
   format.  (fingers crossed)
 * Fixed a bug that caused things to get marked as
   user defined when the bag scan auto junk'd them.
 * Added a new junk type 'icky food' which is old,
   flat, congealed, etc food.  Disabled by default.
