Wemail

Added

- `filter` command - filters all messages in current folder.
- `ext` command - allows viewing different parts in external viewers/editors.

Changed

- No longer wrap body lines, because it was wrapping the wrong way.
- `ls` display no longer shows filename, but email subject

Added

- `links` command now parses URLs from the message body.

Changed

- `body` now displays the message body interactively if it's too long. It also
wraps the message at 120 characters wide, or the width of the terminal -
whichever is smaller.
- Header wraps message body, so truncating should be a lot nicer. Also wraps.

Fixed

- Update from the prompt no longer quits if there are no updates.

Fixed

- Update from the prompt now actually works, instead of throwing an error.

Changed

- Saving without a folder now saves to `saved-mail`

Fixed

- Forwarding and replying now both allow attachments and CommonMark rendering.

Changed

- Message now prints when you're up to date.
- From address tries to default to ones found in config.
