Include visualizations in a job clone

[wiwofone]

Sat down and fiddled a little with the source code. Was trying to see if I could add a feature me and some other people have needed for a while. Please feel free to discuss this, would love for this feature to be available. Just figured it might be easier if someone started with it =)

Note: the change required some changes to the fields that were published with visualizations as children of jobs. I haven't worked with Meteor enough to know if this is best practice.

Also, my linter removed some unnecessary spaces, guess that doesn't hurt.

Good stuff, thanks for the PR! Overall looks good, but gonna comment on some minor things. Happily merging after that.
