Subject: [PATCH] better behaved models for undefined attributes

only effects merge_attributes (and therefore initialize)
for any non-attributes (except collection/connection),
values just get trown into model#attributes,
but won't show up as accessors or in inspect, etc.
Results in no errors, but implies that the attributes SHOULD be added.
