0.6.0

New features/bug fixes:

• support <mj-include> for body components
• mjml_to_html(): also accept plain strings as input
• add support for json-like dict as input
• avoid deprecation warnings about invalid escape sequences in regex patterns
• add support for <mj-font>, <mj-preview> and <mj-raw>
• better error message for unknown tags

I'd like to highlight that many of the features mentioned above were contributed by volunteers:

• Pascal Corpet (@pcorpet)
