Add 'browser_version' to browserstack capabilities?

[christinetwo]

I added '->scalarNode('browser_version')->end()' to the children for getCapabilities in BrowserStackFactory.php. This allows me to select the browser version. I'm wondering why this was not included as it is one of the capabilities BS will handle?

Thanks! And Thanks for building a super useful extension!

I think this key should be on the selenium2 Factory/Driver. It's an alias for the "version" capability, and it's still used in someplaces.
