971140 - Fixed issue with CVD vs CV permissions

Changed controller instances to state that
1) Content Views are deletable if user has perms to delete the
Definitions of the content view. Previously user required publish
permissions to delete content views.
2) Another fix was to show the Remove link for content view definition
if the user had "delete" permission.
