Use invisible recaptcha

[iambibhas]

Fixes #143.

This essentially forces invisible recaptcha wherever RecaptchaField is used. On any client app that uses this, it's required to set this in the config -

RECAPTCHA_DATA_ATTRS = {'callback': "onInvisibleRecaptchaSubmit", 'size': "invisible"}

@vidya-ram there is a confusion between formid and ref_id in renderform macro. formid isn't used almost anywhere. Rather ref_id is dynamically generated and used as id for <form> elements.

[jace]

formid is submitted back to the backend as the form.id variable. It is used when the same endpoint handles multiple forms, to identify which was submitted. It is only used in the frontend to create a hidden input field, with name="form.id" value="{{ formid }}". As a value rather than an id, it is not useful in JavaScript.

You need ref_id here.

1. If you must change the method signature, issue PRs in every repo that calls the method.

2. We're maintaining feature parity with the Bootstrap templates since they are not discontinued until all the Bootstrap apps have been shut down or migrated.

Changing the parameters will break a lot of code. Add this to the end as optional values. https://github.com/search?q=org%3Ahasgeek+rendersubmit&type=Code

[vidya-ram]

This function can be added to widgetscripts macro and form, ref_id need not be included as parameters in rendersubmit

[iambibhas]

Added the scripts to widgetscript and no longer modifying submit button.

On any client app that uses this, it's required to set this in the config -

RECAPTCHA_DATA_ATTRS = {'callback': "onInvisibleRecaptchaSubmit", 'size': "invisible"}

If this is required everywhere, why is this config? It should be just code.
