Checkmk Werk 7428: email: don't escape email subject and addresses

ID: 7428 Title: email: don't escape email subject and addresses Component: Notifications Level: 1 Class: Bug fix Version: 1.7.0i1 Since version 1.5.0p14 the subject and addresses of HTML emails were escaped, i.e. the characters '<', '>' and '&' were replaced by '<', '>' and '&', if present. This resulted in a slightly more unreadable subject if any of these characters were present and if an email address contained an ampersand it would result in an invalid (escaped) email address.
