Add generic xref group/source admin pages to liberty

LibertyXrefType: add getContentTypeGuids() and getGroupList() static methods.

New admin pages with package filter (session-persisted content_type_guid
dropdown): admin_xref_groups.php manages liberty_xref_type rows;
admin_xref_sources.php manages liberty_xref_source rows. Both support
add and delete (delete guarded by entry/source count). Wired into
menu_liberty_admin.tpl as Xref Groups / Xref Sources links.
