Feature Request: Add method to programically submit form in withFormsy hoc

[th3fallen]

Title pretty much says it all

[broofa]

Would also like this. Use case is embedding a form within a modal dialog component that has the "OK" and "Cancel" buttons as part of the boilerplate markup. I'd like the dialog "OK" button to submit the form.

It's possible christianalfoni/formsy-react#45

Then this is a documentation problem, and should still be a PR.

This is the function mentioned christianalfoni/formsy-react#45 (comment)

It would be a very easy first PR to: 1) Create a test to make sure this functionality is not broken in the future, 2) Add it to the documentation.

But in the meantime, this at least solves @broofa's issue.
