Part 2 of 2 for "Log-on not successful" bug when using ProtonMail.

The curl login check uses the imap(s) protocol, which means it will use
the default ports. However, when using ProtonMail, these ports are
different (namely 1143 instead of 993).

We now use the port variable in the curl login command, defaulting to
993 when the port was not overridden.

The port variable was already set when the ProtonMail flag (-p) was set.

Part 1 of 2 for "Log-on not successful" bug when using ProtonMail.

The curl login check defaults to `imaps` when `protocol` isn't set.
Because ProtonMail isn't using any TLS, we have to use the `imap`
protocol.
The `protocol` variable was never set, so now we set it when the
ProtonMail flag (-p) is set.

Fix mailboxes on macos

The Mac version of paste requires "-" to read from STDIN. Without "-", the "mailboxes" line in ~/.config/accounts/<email address>.muttrc is empty upon adding a new mailbox via `mw -a <email address>`. The Linux version of paste works fine if "-" is added.
