Remove unused coffee file
Add some JavaScript actions. WIP.

I'm trying to avoid using backbone for the login
screen and just use plain jQuery with require.
It's a lot messier.

This code needs a lot of refactoring.
- add a remove text button when text is present in input box
- add a submission click handler to anchor
- prevent submissions faster than every second
- add some basic code to detect when there's something to remove
  and show and hide the remove button when there's at least 1 character
- remove bootstrap.js from login page, we're only using the CSS
  for now.
- use a relative span to position the remove button span within the
  input box.
