[RFC 0/1] de-quote quoted-strings in mailinfo

This is my first 'big' C patch, so first an RFC. 

This patch implements RFC2822 dequoting of quoted-pairs in quoted strings, which was not done yet. This means removing the "\" as escape character from header fields, but only quoted strings, and comments (text between braces).

According to the RFC, comments can also appear in square brackets in the e-mail domain, but that has not been implemented. In fact, just like other functions, it just looks at the whole header line.

Please let me know what you think.
