Get IP adresses automatically

[k-nut]

The checkbox is already there but we do not make a request yet to get new IP adresses

@andrenarchy @k-nut what do you think of registering ips after clicking on "save" button and handle the results in a dialog? I implemented the basic gui stuff in the last commit. if you don't complain I would continue with that :)

Hitting save can trigger two things:

• issue VPN03 certs
• register IP addresses

When hitting 'save' (maybe we should rename it to 'register' or something similar), the certs and addresses should be registered as pending. The user should receive a mail with a link to the certificates and IP addresses. Only when the link is clicked, the certs and addresses will be actually registered.

In my opinion, the most user friendly solution would be to add a 'code' to the mail that can be copied+pasted into a dialog box or a text field that pops up below the save/register button. The certs+addresses can then be pulled from JS code. What do you think?
