pg_json.rb requires dirty_minder but doesn't use it

[systemed]

Unless I'm mistaken (always possible :) ) it also needs:

include ::DataMapper::Property::DirtyMinder

[xentek]

hmm, i'll have to play with this. It's been a while since I built this and not sure if that require was copy+pasta or was needed for some obscure reason. Likely the former. I'll see if including the module actually enables dirty tracking and see if I can't add that behavior to all of the types in this gem.
