aerc: use aerc as an mbox viewer

Use Aerc as an mbox viewer. Open an mbox file from the command line in a
new tab with the mbox backend. Provide a convenient and quick way to
display emails from an mbox.

Usage: aerc mbox://<path>

where the path can either be a directory or an mbox file. If it is a
directory, every file with an .mbox suffix will be loaded as a folder.

The account config will be copied from the selected account. This allows
the answer emails in the mbox account.
