#906358 by das-peter, meba, yched : fix a couple notices in cck "php code for default value / allowed values"

Add installation function to content migrate that will swap the stored content_extra_weight values to the new field_bundle_settings variable. Also properly set the body weight, which is otherwise not right.

#781088 More work on content migrate. Fix allowed values to make them into arrays, to match the new way that lists are stored.

node_reference and user_reference field types now live in the 'references' project - http://drupal.org/project/references

Kudos @swentel and @stalski for moving the code forward and taking over maintainance

still requires core fix in

Revert #780566 by stella, add drupal_alter() for content_allowed_values lists created by userreference and nodereference, needs more thought.

Set up CCK module to handle the php allowed values code, still needs more work but this creates the tables and displays the values in the right spots.

Also need to re-name the autocomplete module to the new node_reference and user_reference module names.

More tweaking of content migrate script, starting to work correctly for at least the cases I have tested so far.

Adding content migrate module. Still needs lots of work, just getting this much committed so it is not lost.

Fix fatal errors when enabling cck and fieldgroup by removing install schema. Add entity_type to cck table.

Remove all the code for extra fields since that is now in core and not needed, alter the description and title of the module. Leave some helper functions and permissions to do things like handle php code used to set values in the D6 version.
