RecaptchaV2 1.0.0-rc1 fixes for Login package compatibility

# ReCaptchaV2

ReCaptchaV2 integrates Version 2 of Google's ReCaptcha service into MODX as a FormIt hook.

It can also be used with the Login Extra as a preHook, as of version 1.0.0

You must generate API keys for your domain here: [https://www.google.com/recaptcha/admin](https://www.google.com/recaptcha/admin)

and enter them into the System Settings before you can use ReCaptchaV2.

###USAGE EXAMPLE:

```

[[!FormIt?

   &hooks=`recaptchav2,email`

   ...

]]

```

OR

```

[[!Login? &preHooks=`recaptchav2`]]

```

You will also need to call the accompanying form element renderer snippet somewhere in your html form, for example:

```

<div class="form-item">

    [[!recaptchav2_render]]

    [[!+fi.error.recaptchav2_error]]

</div>

```

I tried making the render snippet usable as a preHook for FormIt but ran out of time. 

This Extra is maintained in Github: https://github.com/sepiariver/recaptchav2
