On case-insensitive filesystem,
`inbox` and `Inbox` are the same path.
Running `find Inbox inbox [expr]` will print twice the same information.

Use shell glob instead:
`find` will descend into path `inbox`,
ignoring letter cases, only once.

Fix #828.

To close #845 :

I added the `-x` flag to prevent the regex from matching on _every_ pro-
cess name containing an `X`.

Because I'm not entirely sure about portability (does every `pgrep` va-
riant support that flag), I didn't push this directly.

So what do you think @LukeSmithxyz ?

Also better formattin

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

in accordance with #694

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.

inside .zprofile and .zshrc.

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

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

* 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.

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.
