- a few additional MIB tree management methods added to MibViewController

  to better address ordered nature of MIB tree nodes (namely, getFirst*,
  getLast* family of methods)
- rfc1902.ObjectIdentity() now accepts 'last' keyword parameter to
  position on last (otherwise, first) object in given MIB module.
