Stopping basic spam bots from filling contact form

[avicndugu]

This is an enhancement or feature.

Summary

With this new feature, a hidden form field stops spambots from filling and submitting your contact form without using third-party services.

This will not stop human spammers and sophisticated spam bots.

Context

To stop spammers, many sites use Google reCAPTCHA and other similar services. These services use a private key that requires a backend(server or serverless function). This solution is for static websites that don't have a backend solution.

This is related to Github Issue #19

Sorry for the delayed response here, any chance you could clean up the whitespace in the diff @avicndugu (thus reducing the diff to only the needed lines changed)

Thank you for taking the time to implement this! I appreciate you

I've cleaned up the whitespace in the diff.
I can't figure out how to clear the diff on some two lines so I'll leave it at that.

• [nitpick] The comment contains a typo ('Disable's') and could be clearer; consider updating it to explain that the form only submits when the honeypot field is empty.

if(username === ''){ // Disable's form submit if hidden input(username) has been filled
