Honeypot, more customization options and more hooks

[pvankouteren]

Here's what I have customized in my own project to make it more flexible:

• Honeypot protection for spam bots (these get an ok message as well, without adding it to Mailchimp)
• Customization of texts (also good for translation)
• Option to set the amount of days to hide when te popup is closed
• More hooks for particular events (handy when using Google Analytics' Event Tracking for example)
