#240102: (Largely by neclimdul) -- Initial pass at profile field handlers. Still 3 @todo items remain but they are not hard.

#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)

Templateized exposed filters; exposed filter memory; exposed filter smoothing. Mostly done with exposed filters now; leaving exposed sorts for later.

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

Add basic support for summary styles; they don't quite work yet because view URL knowledge isn't implemented.
