workable mailsync readded to enable autosync

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

-- Provides sensible defaults and an attractive appearance for the neomutt email client
-- If mutt-wizard doesn't know your server's IMAP/SMTP info by default, it will prompt you for them and will put them in all the right places.

 ## Watch out for these things:
-- Gmail accounts can now create 'App Password' to use with """less secure""" applications. This password is single use (ie. for setup) and will be stored and encrypted locally. Enabling third-party applications requires turning off two-factor authentication and this will circumvent that. You might also need to manually "Enable IMAP" in the settings.
-- Protonmail accounts will require you to set up "Protonmail Bridge" to access PM's IMAP and SMTP servers. Configure that before running mutt-wizard. Note that when mutt-wizard asks for a password, you should put in your [bridge password](https://protonmail.com/bridge/thunderbird#3), not your account password.
-- Protonmail bridge is prone to timing out. Watch out for this while adding an account. If the bridge times out, try again. It might help to [increase the timeout](https://protonmail.com/support/knowledge-base/thunderbird-connection-server-timed-error/) in your `mbsyncrc`.
-- If you have a university email, or enterprise-hosted email for work, there might be other hurdles or two-factor authentication you have to jump through. Some, for example, will want you to create a separate IMAP password, etc.
- - `isync` is not fully UTF-8 compatible, so non-Latin characters may be garbled (although sync should succeed). `mw` will also not autocreate mailbox shortcuts since it is looking for English mailbox names. I strongly recommend you to set your email language to English on your mail server to avoid these problems.
