Please don't wait a month to merge me..

Next batch of template updates, making things use bootstrap 3. In summary:

* Make things use the `base_new.html` template for bs3
* Checking that they still work
* Making the `/reads_vs_qv` page not depreciated any more, as it seems to work
  * I also made the default range the last two months instead of the last 4 years. Loads much faster now.
  * Some good 'ol loading spinner action at work again
* Changed the structure of the navigation a little..

Testing here if I'm around: http://130.229.42.149:9761/
