Easier to track if we leave the original files alone. Actual changes to the
doxygen style:
* indent <dd> blocks
* hide the navigation sub-items. Our current style expands the full navigation
menu but File-list, etc. is mostly useless and just wastes space.
* force some space below the main bar
* change the header sizes around a bit. Primary goal here: making <h1> smaller
than the title
