allow options.* as event handler callee

[Conduitry]

Gitter convo.

This is a little hacky, as the handling of options.* is different than other things that are already in there. It's not like set/fire/destroy, as we're calling options.something(), not just options() - and it's not like this/event/console, as those variables already exist in scope, and for options we need to output component.options.whatever().

I think your idea in Gitter of using options for this is a good one - you don't even have to put the functions inside data, you can use whatever layout you want. This PR removes the warning about using options.something directly in an event handler.
