Fixes for bug #66308 ([embed] XPIDL'ize transaction manager) 

sr=sfraser@netscape.com,mscott@netscape.com r=jfrancis@netscape.com

* nsITransaction, nsITransactionListenter, nsITransactionManager have
  been XPIDL'ized and moved into mozilla/editor/txmgr/idl. The versions
  of these interfaces in mozilla/editor/txmgr/public are being CVS removed.

* Renamed Do(), Undo(), and Redo() to DoTransaction(), UndoTransaction(),
  and RedoTransaction() to avoid reserved word problems in languages like
  JS. I did a sweep through editor and mailnews to remove these methods.

* PeekUndoStack() and PeekRedoStack() now return an AddRef'd pointer.

* Removed GetUndoString(), GetRedoString() and Write() from the
  nsITransaction interface. Neither editor or mailnews really made
  use of these methods.

* Removed Write() from the nsITransactionManager.cpp interface.

* The Transaction Manager now supports weak references.

* Added support for nsITransactionList to the TransactionManager
  to allow access to all transactions on the Undo and Redo stacks, as
  well as auto-aggregated transactions.

* Removed all references to nsITransactionDescription from txmgr and editor.

* Added nsPIEditorTransaction and made all Editor internal transactions
  inherit from it so we can distinguish between our transactions and
  ones from 3rd parties.
