Added images the algorithm is currently failing at.
Fixed the follow_scroll directive to handle resizing, refactored it a bit, and made it work for the left side (photo).
Misc refactoring. Updated histogram and palettefromphoto services to use keyword arguments. Added some putsing during photo fetches from 500px.
BUGFIX: switched bg-colour to border-right on the palette, since <6-colour palettes were giving the impression of duplicate colours.
Created a test bed page for quick algorithm refinement. Made a few improvements (I think?).
