Bug 390331 - preDelete and postDelete not called for Patterns

*Corrected call delegates so that initially pattern is called, delegates
to DefaultDeleteFeature and that calles own pre and post delete hooks as
well as pattern pre and post delete hooks
*Same fix done for remove pre and post hooks
*Post hook calls occur in inverse order to ensure "bracketing" of the
calls
