Contact and Book A Tour: submit button should be disabled by default

[mcuclev]

Steps to reproduce:

1. Access the new web-boost-based version of the website. (Currently "_dev" branch)
2. Navigate to "Contact" or "Book A Tour" in any language.
3. Try submitting an empty form. (Click "Submit" or "Schedule your tour")
4. MailChimp's default error message "Please enter a value" is displayed in English only.

Expected result: Localised error messages.

Actual result: Error messages displayed only in English appear from MailChimp resource.

Please, refer to the attachments for actual result:

To avoid receiving these MailChimp error messages which are difficult to capture and translate in the project itself due to structure of the MailChimp plugin written by @ddimitrioglo, it would be wise to disable the "Submit" and "Schedule your tour" buttons until every required field is filled in.
