Ref to table_map from BinlogEvent

[zaibacu]

Not really a issue, but a feature request.

In my use case, it would be very valuable to have access to table_map from binlog_event to get column info. Not quite sure how it goes on other versions, but in Mysql Docs they claim, that inside metadata block, we can find column names.

I guess I will try to do it myself, just a heads up, maybe there's a way to get this info, I just don't see it :)
