This patch removes the differences between the JavaScript loaded in
edit and view modes.

  * increases the amount of JavaScript that is loaded initially
  * decreases the number of requests
  * only one cache for all javascript
  * all javascript is available in view mode

The last point is the most important as it makes a lot of functionality
available to plugins working in the view mode. The discussion plugin
now can reuse the toolbar code for example.
