Remind users to edit paths on install

[k1o0]

Is your feature request related to a problem? Please describe. A user forgot to edit their paths file after installing Rigbox.

Describe the solution you'd like Add a link to the documentation at the end of the install and a reminder to edit the paths. Make the user press return to indicate that they understood.

Could also throw an error in the template paths and explicitly tell users to remove the error line after editing their paths.
