fixed an install bug (bad sql if enabling views *after* subform, and subform does not yet have any defined relation types)

added an option to require delete confirmation
added support for keeping fieldsets open between page loads
fixed a child type calculation bug
added views cache clearing on subform creation (without this, views driven selection lists won't work)

improved selection list (views integration) with working filtration and paging
tweaked css (looks more like a tree view now)

create branch 'DRUPAL-4-7'.
