Admin page JS refactor into module

[dhasegan]

• Check the current implementation of modules explore.js forum.js course.js
• check how it all links together in connect.js
• how python builds up the js files in settings.py
  • variable PIPELINE_JS
  • optional PIPELINE_JS_COMPRESSOR
• check base.html to see how we include js files
  • {% load compressed %}
  • {% compressed_js 'connect' %}
• check utils.js for easier ajax form submission
• rewrite the code needed, as explained in the title of this issue

(after you understand what you have to do it will take 10-15 minutes to refactor)

looks pretty good and easy to understand. On it now.

p.s: funny how it all links together in "connect.js" ^_^
