misc fixes

[delthas]

some fixes i had to add to make irctest work for my ircd.

running the tests on non-oragono servers is broken right now, even with these fixes, because some test cases with oragono tests still call setUp, tearDown that end up calling oragono-specific functions on the controllers, like baseConfig and addMysqlToConfig.

as a hotfix i added to my controller:

    def baseConfig(self):
        return {}

    def addMysqlToConfig(self, config=None):
        pass

also changed the run function to:

 def run(self, hostname, port, password=None, ssl=False,
            restricted_metadata_keys=None,
            valid_metadata_keys=None, invalid_metadata_keys=None, config=None):

because the tests need the config parameter even though it's oragono specific stuff.

so yeah the project is kinda broken for non-oragono servers anyways but here's some fixes for issues i had.
