Improve VPN certificate name generation

[vrrc]

When creating a certificate for a VPN using the included wizard, it would be nice if:

• The blue "wizard" button that's on the right should be on the left. If you don't create certificates too often it's easy to miss that you can enable/disable the assisted certificate creation which changes the name of the about to be created certificate.
• When using the wizard, if any field is empty, don't add hyphens in the name. I.E. if just filling name and surname, the wizard creates a name like "ORGANIZATION---name.surname-00" instead of "ORGANIZATION-name.surname-00".
• Finally, the "wizard" button/feature could be renamed to something like "name patterns", so new patterns can be added. Even a feature to add user defined patterns could be useful here.
