Gnats 4597: Crash clearing workspace with more than one open RuleSet Dialog
FIX NOTES [8-26-2008, Phil]

---------------
RplDlgMgr.cpp
---------------

FIX in RplDlgMgr::closeAllRplSetDlgs (bool):

After calling RplBaseDlg::close(), remove the dialog box from the
_rplDlgs map by calling RplDlgMgr::removeRplDlg (RplObj*, RplBaseDlg*).

---------------
RplBaseDlg.hpp
RplBaseDlg.cpp
---------------

Diagnostics enhancements:

(1) An actual destructor was defined, for diagnostics.
(2) RplBaseDlg's now have serial numbers:

  static int _rplBaseDlgCnt;
  const int _rplBaseDlgNum;

Sample trace confirming RplDlg deletions:

  RplBaseDlg ctor [#1] 'RplSetDlg' 49a05d8
  RplBaseDlg ctor [#2] 'RplSetDlg' 4a8f438
