0.6.0: 
- can now handle text/html multipart sort of mails. It uses the text part, not the html one, because it contains something like "<HTML>" or "<BODY>", which could destroy a webpage and I really don't want to parse html-code!
- Also a bug fixed, which was happen when one has sent a Mail without a subject (or ""), the resulting page was 0 byte! Why? The file was opened, _before_ the subject line was checked. Fixed now. The result page will be opened when needed.

0.5.0: initial public release.
