Update 0.15 to 016
------------------
0.16  2015-09-22T00:17:07Z
      - Added new abstract class, URI::_odbc, for URIs that use ODBC in
        `dbi_dsn`.
      - The `dbi_dsn` method of URI::mssql now returns an ODBC DSN instead of
        DBD::Sybase, since the latter would require Sybase to build.
      - URI::sqlserver now inherits from URI::mssql rather than the other way
        around.
      - Fixed a bug where a URI with three slashes but no authority part after
        the first two would incorrectly think the databse name should be an
        absolute path. That is, in "db:sqlite:///foo.db", the `dbname` value
        is "foo.db", not "/foo.db". Thanks to Dan Book for the report
        (issue #8).
