pretty easy to find on their website, yet a short timesaver for students who bump into this in the future

I contacted MUTT irc channel to solve severe lags while navigating mailboxes of certain email providers with IMAP) (the emails were not stored locally). After extensive testing, changing the default value of mail_check from 5 to 60 solved my problem. I propose this change because several other people might encounter the same problem (especially yahoo users)

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

Update domains.csv

Added website

Added ethancoe.com

restore default text color on 'Ctrl-C' exit

The terminal text color  wasn't reset when the user  aborted the wizard
while being prompted for input.
This resolves https://github.com/LukeSmithxyz/mutt-wizard/issues/224

Add RMIT student email

Added Carleton University student email domain to domains.csv

Added address for politecnico di milano university

fix: vivaldi settings

Use different SMTP server port for onet.pl

feat: add vivaldi.net to known domains

IMAP mail.vivaldi.net 993
SMTP mail.vivaldi.net 465

Even though the following official help page says that port 465 should be used, this didn't work for me (msmtp just hang indefinitely).
Instead port 587 seems to work fine, even though I couldn't fine some official document by the e-mail provider mentioning it.

If someone else can confirm that indeed, 587 works for them as well, feel free to merge this PR.
