Main fix - header / nav objects

Fixed nav objects: slightly darker border; rid of nav bottom border to
blend to header bottom border; changed h2 to target just nav h2’s
instead all h2’s; added standard transform to work in firefox and all
new browsers; nav h2’s moved up 10 pixels to look cleaner

Adjusted header: erased first hr and replaced with border-bottom to
header to make it easier to flow nav into header; took one pixel away
from height to fix nav objects

Header: erased unneeded bland, img alt provides placeholder while img
missing
