Add an options mechanism for renderers

Hmm, this requires a specific setting to be passed in to the accordion widget, i.e. autoHeight: false. So the real issue here is allowing options to be stored per renderer type. I guess we'll just have to add one more field to the Quicktabs table that stores a serialized blob of options, or else put everything in the renderer field. Needs some thought...

OK, the more I think about this the more I realise it is really needed. Shouldn't be a big deal though - the QuickRenderer class will have an optionsForm() method that returns form elements for capturing renderer-specific options (using the #states property we can make sure they aren't visible unless that renderer is selected) - these get stored as a serialized array in a new options field in the Quicktabs db table.

I definitely want this in the next alpha release and will hopefully get to it at the weekend.

Yep, try it out - there's an update hook to get the options field, and then if you already have a QT instance set up as accordion, you'll need to resave it because if you don't pass the "autoHeight: false" option, it defaults to true. I haven't added any other options yet but the main thing is having the mechanism there and then any renderer can add whatever options it needs.
