Mailchimp merge vars are broken

MailChimp merge vats have the syntax *|VARIABLENAME|*. The problem is that the | character is replaced by premailer with %7C, so MailChimp won’t parse the variables.

This looks like a duplicate of #72, which contains a link to some code that you can use to turn the inlined HTML into a string without content in attributes being escaped. See the linked issue for more info on what is happening.

There is another case: any smarty template contains variables using { and } almost anywhere in the document. Probable pattern: \{[a-z0-9_\.]+\}
