django adapter: to implement base.DatabaseWrapper.server_version property

[GoogleCodeExporter]

This is minor thing, but probably can be useful in the future. 
mysql adapter defines in DatabaseWrapper class server_version property and
get_server_version method in order to make distinctions in some part of the
code depending of the db server version. I have done similar based on PyDB2
adapter like this:

    server_version_re = re.compile(r"dbmsVersion: (.*)>")

    def get_server_version(self):
        """ <open connection at c91a90, serverName: DB2     , dbmsName:
DB2/NT, dbmsVersion: 07.02.0009> 
        this function will return (7,2,9)
        """
        if not self.server_version:
            if not self._valid_connection():
                self.cursor() # creates connection
            m = server_version_re.search(str(self.connection))
            if not m:
                raise Exception('Unable to determine Db2 version from
version string %r' % str(self.connection))
            self.server_version = tuple([int(x) for x in
m.groups()[0].split(".")])
        return self.server_version

Probably this information can also be useful from end-users' viewpoint
(maybe django.db.BaseDatabaseWrapper should have such property/method also).
