Support for renderLine event?

[rgov]

I want to be able to implement the functionality in the indented wrapped line demo, which involves adding an event handler for the renderLine event. But this doesn't appear to be one of the ones exposed by react-codemirror2.

@rgov intersting, I must not have seen this one. Should be easy enough to add. I'll get this in, hopefully soon!

@rgov fixed with the 5.1.0 release!
