Convert base JS file to plain JS

[deivid-rodriguez]

The autodeploy triggered after merging #80 failed. The good news is that autodeploys are working :)

This PR should fix it by converting the base JS file to plain JS since ActiveAdmin 2.0 no longer depends on coffeescript.

Awesome! Let’s get this auto deployed. 😎

It was a bit of a nightmare to get this deployed. The old cached coffeescript assets were still used, but the coffeescript dependency was no longer present, so asset precompilation would fail.

I finally managed to deploy by running

heroku plugins:install heroku-repo
heroku repo:purge_cache -a demo-activeadmin-owned

And then triggering a manual deploy of master.

Not sure if this is the recommended solution for this problem, I got it from this thread. Also increasing assets.version in Rails config is suggested there.

We should probably keep this in mind for the upgrade to Active Admin 2.0, and maybe ask the heroku people about it.

Sounds good, thanks David!
