* changed ping address to a more friendly location 

`1.1.1.1` is not a friendly address for users from some parts of the world (e.g., China). Changed to `example.org` which should be more friendly to access.

* changed internet check by fallback

This is probably better since for most people it does the same thing and the first back up is Cloudfare's other DNS address which surprisingly can be accessed in more places (e.g., China) now. And changed the finall fallback as example.org.

I believe this addresses issue #456 where if you add a protonmail account you get an error.  This is caused by prematurely returning from the case statement that queries whether you have a protonmail account or not.

I think a recent change tried to send output from crontab to dev/null to avoid messages appearing a) when setting the crontab, b) whenever mailsync is run.  However the redirection was for the string concatenation meaning a null string was piped to cron obliterating the crontab (thank goodness for backups). I have put the redirection in the correct location (similar to a few lines above when removing the mailsync line).  I have also redirected all output of the mailsync (both errors and normal messages) to dev null.

If no options are passed but the accounts are specified then the blank opt flag causes a (harmless) error message from mbsync about an empy channel.

Let's make crontab a little quiet here, unless for those who set up mail for crontab error handling will be disturbed every few minutes.

* Simple Fixes

* Tweak wording

* Update openfile

* ShellChecked

* Little Fixes

* mutt-wizard works on FreeBSD, also changed mbsync with isync (actual package name)

* Added pgp support

* Fix head: illegal line count -- -1

* Fix `osascript: display notification with title "📧 xxxx" subtitle "xxxx" : No such file or directory`

use kill instead of pkill for speed

* Added vxempire.xyz to domains.cvs

* Fixed set_folder for vxempire.xyz

According to man page of mbsync, AuthMechs is the correct spelling of the option.

the prefix is not correct at least for Ubuntu distro. Since doc clearly
states the dependencis. We assume msmpt is on the PATH environment.

all i did was add the email to the default status bar configuration

This enables users to easily recognize notifications to be able to

Mutt removes the single quotes, rendering an incorrect password.

In my [PR 224](https://github.com/LukeSmithxyz/mutt-wizard/pull/224), I
introduced a bug.  While I was catching SIGINT with the trap statement,
I did not actually exit the script and returned into the shell.

Fixes https://github.com/LukeSmithxyz/mutt-wizard/issues/234
