VIVO-224 Get rid of MANAGE_PORTALS permission

It was only used in editing the application bean, and was equivalent to EDIT_SITE_INFORMATION.
VIVO-224 Get rid of MANAGE_TABS permission

It was not used, probably since we no longer have tabs.
VIVO-224 Get rid of REBUILD_VCLASS_GROUP_CACHE.

Since we build the cache from Solr, we no longer provide the option to rebuild it.
VIVO-224 Change USE_MISCELLANEOUS_EDITOR_PAGES to USE_INDIVIDUAL_CONTROL_PANEL

It’s hardly miscellaneous if there’s only one page.
