Updated GUI and phishy urls

Two big items in this update. The first is the updated GUI. The goal was improved clarity and usability. Contrast has improved, icons and badges were added, asset pages have sticky headers, and things generally look smoother.

The second one are the phishy urls. There was a bug in there that kept detecting a phishy url as new if it was a permutation of two of your assets. Only one could be registered. That is fixed now, and the code had a major review. Phishy urls that redirect to the original url or one of your other assets are now clearly labeled. Babydomains are also clearly labeled if detected, as are reserved domains and redirects to marketing sites.

You can directly add a phishy_url to your assets if you bought it (from the action menu in the right top), and it's even possible to add your own phishy_urls that you want ShadowTrackr to monitor for you. Most should be detected by our algorithm, but some language specific urls (singulars/plurals) can be hard to generate.
