• Added URI::_ado, which subclasses URI::_odbc to provide a dbi_dsn()
  that returns a DSN using DBD::ADO. NOTE: This class is experimental,
  since I was unable to figure out the best default values for the
  connection string -- there are so many options! Feedback and
  recommendations wanted (Issue #11).
  
• The dbi_dsn method of URI::mssql now supports a single argument to
  specify the DBI driver for which to return a DSN. Pass in "sybase" or
  "ado" (experimental) to get a DSN for either of those drivers,
  instead. Based on work by Dan Muey.
