[per-object-permissions] Fixed bug in contains_permission where it was just checking against any permission instead of the given permission

[per-object-permissions] Made changes so delete and "Save and add another" only shows up if the user has permissions
[per-object-permissions] Rewrote the has permission variables in the context for change form to use has_perms and check for model
