Bacon.try missing in docs

[jaidetree]

Thanks to @semmel in #809 (comment) for mentioning Bacon.try. However, looking at the readme errors section it links to http://baconjs.github.io/api3/globals.html#try which is not surfaced anywhere.

I'm down for creating a PR to fix this, but need some guidance on how you'd like me to fix this. My thinking is it'd be worth exposing in the api v3 docs but alternatively, the link could be removed from the readme.

It's now in the docs as per version 3.0.19. The function is named tryF because try is a reserved word. The documentation hopefully makes it's usage clear enough though.

Thanks for updating it!
