Most of user.views.inc plus some bug fixes, improvements to join handling. For those interested in the real complexities, check out views_handler_filter_many_to_one to see cool stuff you can do with joins in views 2 that you could not in views 1

#236786: (by KarenS) Make sure all views.*.inc files can be loaded from the module's path or module_path/include directory.

#105125: (by moshe) Per field access control; fields will now remove themselves from views if the viewing user does not have access to see the field.

Retooled the form replacements into a single, unified form builder (which may be suitable for use in Drupal 7)

#232905: view id was not getting read due to previous patch, thus display was getting saved with vid 0.

Import/export now work, plus an unfortunate major overhaul underneath. THIS CHECKIN WILL BREAK ALL EXISTING VIEWS.

Add better hiliting to the UI; now possible to tell what items are overridden as well as what item is currently being edited
