The macOS version of `pidof` doesn't implement the `-s` flag.

in accordance with #694

This reverts commit c95428f0f1.

A user reports notifications not working on their setup because there is
no display id  contained in the `ps`/`pgrep` output  concerning the Xorg
process.

This commit checks if there's a display server running at all, and if so
it sends notifications even if there's no display id.

Resolves https://github.com/LukeSmithxyz/mutt-wizard/issues/661

remove old vars like pass_prefix, muttdir
reorder mailbox detection to find inbox case and later delim
offline delim set to _ which should avoid most issues

inside .zprofile and .zshrc.

~/.profile is not necessarily present when using zsh for login and
setting $ZDOTDIR in ~/.zshenv

When the transition is made from an offline profile to an online
profile, there is still someone else's macro - side effects...
Variables, macros, and so on must be taken-into-account
**symmetrically** with any of the `mutt-wizard`'s profiles.

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.

cloe #367

rm mbsync requirement for online storage

the new script manually searches for environmental variables
so that it can work from a cronjob
and additionally searches for all Xorg displays on Linux
so that the display notification should appear correctly
no doubt there will be more bugs, but this is what the people want
and it's worth working out
