Track client-side JavaScript errors Rollbar.js

[ostermanj]

I've set up Rollbar.js error tracking on a free account. It will capture and organize any uncaught JS exceptions being thrown on users machines. We'll see if any users are getting errors we're not yet aware of.

I can add any contributors who want access to the reports.

I'd like to be added!

Cool. You should get a notification from Rollbar.

It's on my free account that allows up to 5,000 events / month. I have one other project on there so it may top out. If it does we can consider opening a separate account. Set up is easy enough.

@ostermanj
I'm happy to create an account (might have one) under the Code for DC banner

[NealHumphrey]

@mkalish that would be helpful!

@NealHumphrey @ostermanj
I'll set up an account tonight

[ostermanj]

@mkalish when you have the access token I'll change it on master. Thanks!
