Restructuring image locations.

Work-in-progress commit. Moved images into folders with their projects
inside of publish/ (so they don't get copied over, but are still easy
to find).
Stop using a submodule for media.
Project link image sizes with fixed max height.
Reworking the structure of the page to be simpler.
Bigger text, things are starting to be properly aligned again.
Cleaned up links to images; should all be local and in place.
Stylistic consistency, switch to title-case.
Slightly modified about page.
Smart quotes.
Some documentation for Lure.
Added Lure to the list of projects on view.

Updated about page info (remove twitter from see also, added youtube).
