or just password for admin

Is your feature request related to a problem?

I'm having problem with the hardcoded admin for the account name that stalwart-cli uses. It is having account name admin in the web interface what feels wrong.

I wasn't aware of using : to --credentials when I opened that issue.

With this patch has the help these lines:

  -u, --url <URL>                  Server base URL
  -c, --credentials <CREDENTIALS>  Authentication credentials
                                       accountname:password
                                       orJustpassword
                                   (for default accountname 'admin')
  -t, --timeout <TIMEOUT>          Connection timeout in seconds

Previously it was

  -u, --url <URL>                  Server base URL
  -c, --credentials <CREDENTIALS>  Authentication credentials
  -t, --timeout <TIMEOUT>          Connection timeout in seconds

New version has information default accountname and about the colon for expressing another accountname.
