Add simple view api for add job to view

Hi,

I have add simple api section to handle view actions. Start with addJobToView action
I'm not python developer and i have not python dev environment.
So this code isn't tested, sorry :-/

Can you test this ?
This is part of the issue, that i created on the jenkins-autojobs project
https://github.com/gvalkov/jenkins-autojobs/issues/21

Thanks a lot
