Footer links assume the instance is running on monicahq.com

[rreuvekamp]

The footer seems odd on a self-hosting instance.

• The link "Send me an email" points to "regis@monicahq.com", not to the sysadmin running the instance.
• Privacy Policy goes to monicahq.com and starts with "When you create your account, you are giving the site information about yourself that I collect. ". If the Privacy Policy points to a page on the self hosted instance.
• Release Notes pointing to monicahq.com seem off to, as it's not guaranteed the self hosted instance is running the latest version shown in the release notes.

All valid points. We need to change that.
