[bpel-dev] Reconciliation improvements

["Dennis Ushakov" <dennis.ushakov@xxxxxxxxx>]

Hi all,

I've made reconciliation algorithm to work fully incrementally. This
improvement is based on the fact that ReconciliationBPELReader doesn't
need to re-read those children of DOM element that already have
correspondence in EMF tree. These children will be notified anyway.
Reconciliation now works significantly faster.
Oleg has already committed this fix.

Thanks,
Dennis
