Onfocus support

[mauriciominella]

Reasons for making this change

I'm currently developing a JSON Based Configuration editor, where I'll have a split screen where the Form and the raw JSON will be displayed side-by-side. One of the requirements is to highlight the correspondent field on the raw JSON split as soon a field is focused on the form. Currently only onBlur event is supported, so, I've added onFocus support.

LGTM. Please just remove the added package-lock.json, we don't want to version this file with this project.

@n1k0 Thanks for the heads up. I've just removed the file as requested.

@n1k0 I was hoping to use this onFocus support in a project, any chance a new release is slated soon?

[EDIT]: I'm just jamming my onFocus into formContext until this gets released. Works well enough for now :)

Next release will hopefully happen this week, stay tuned.
