undefined class/module error on load_document about couch_potato

[langalex]

looks like this is a bug with rails and the json gem. the exception occurs not in couch potato but in json, which doesn't like the fact that rails has unloaded the classes in development mode. as this is not a couch potato issue couch potato should not fix this. i would like to provide a workaround though, but i don't have one yet. we would somehow have to reload the classes that have implemented the persistence module before trying to load an object from the database.

i have included a patch in 0.2.16, it only gets loaded via the init/rails.rb file so if you are not on rails nothing changes
