Track the IP address of the operation owner, and the user agent

Please review.

Thank you all for the work! I like the idea.
However I believe we need a way to overwrite the view, because if the module was previously installed, the view won't be refreshed to contain the IP and user agent fields.

How could we do this?

Hi @florianmuellerch,
I don't like the idea of adding new fields to an existing user's view.
What if the module users have already used a customized view? Overwriting the view may break something.
