Test fixes, Land back on #test after QUnit tests and removes calls to console.log
Preloader never got to the images on the current view
Updated image loader and tag removal

We had several problems with our HTML to DOM processor:
- We removed script-, style- and link tags in an insecure way, by initializing the DOM and then remove the tags.
- The images src attribute were updated twice.
 - First to the correct path
 - Then src were moved to the data-src attribute to be loaded as needed (on scroll).
 This gave us the problem, that some browsers first attempted to load all images with the wrong path (404)
 and then attempt to load all images before src were moved to data-src.
 Other browsers only maneged to load some of the images because src were changed.
 The move src to data-src is now done via regexp, this removes the need for the hideImages function.
