Find a way to preview HTML message

[soywod]

When you need to open an email in your browser for example, the flow is not so smooth. You need first to message read --html --no-headers > email.html then chromium email.html. If images are in attachments you cannot see them. This issue stands for finding a smoother alternative.

A first idea could be to split the read command into 2:

• read (for everything related to reading text content)
• export (for everything related to exporting/moving messages). The --raw flag disappear and would be the default behaviour of the export command.
