Allow overriding of target class when using clone_obj
form update from develop
deepcopy cloning rules instead of accessing them directly, so temp rules changes do not persist beyond the point where they are needed
added globalize method to base model, which will auto-create the associated global record. cascades not yet supported (next commit)
global object changes, now handled via a column (specified in the Meta via 'global_column') instead of an association class, to avoid filesorts
reorganization of some utility function, new before_flush sqla event added to auto-globalize new objects if a specified parent is already global
is_global changed to is_globalized
wrong attr name, oops
added baph version of LiveServerTestCase, moved fixture functions to a mixin
added a logger to help with debugging cache issues
Changes to avoid deprecation warnings regarding simplejson
