RunnerCatalogue metadata can be empty/non-existent (eg non-horse events)

[oughtotrade]

In the betfair documentation, a RunnerCatalogue's metadata is not mandatory. For some sports/events, particularly non-horse racing, metadata is not returned. Betfair RunnerCatalog

However in bettingresources.py#L190, metadata is configured as mandatory.

Since release 1.1.2, list_market_catalogue method fails when it tries to make RunnerCatalogue resources as part of the MarketCatalogue resource.

In this traceback, debugging showed that there was no metadata in the runners returned by listMarketCatalogue: {u'handicap': 0.0, u'runnerName': u'San Antonio Spurs', u'selectionId': 237471, u'sortPriority': 1}

Traceback:

Sorry missed this, just pushed 1.1.3 through to PyPi, let me know if you find anymore.
