Disable the twitter job and comment out the gem dependency

Is your feature request related to a problem? Please describe.

By default, users that installed Smashing must edit files prior to running smashing, unless they have the Twitter gem.

Describe the solution you'd like

I think the user experience could be better by giving the users a sample dashboard that works in all environments. We can leave the job disabled, and the import in gemfile commented. So if a user wants to see the Twitter data, s/he can still do it.

Describe alternatives you've considered
