Reduce spam from contact us form

[JoeProgrammer88]

Client is reporting 40 - 50 spam emails per day from the contact form. We need to explore and implement a solution to reduce/elimate these emails.

• Google CAPTCHA could help reduce the spam
• Forcing the users to submit emails from their own email instead of just filling out the form could also reduce spam by letting standard email filters do their job

Client is happy with the solution implemented in #297 They report no need to bring a contact form back
