Fix title area minimum height

If on the bare ska.org domain without additional "Shotokan Karate of America" element above the site title, title area was not large enough to push menu to bottom of header
Set larger minimum height so menu is always lined up with the bottom of the header
Scroll logo with content when it is centered on medium-width devices

On medium-width devices, set header container to relative positioning, but set the title area and menu to fixed positioning and apply background color to scroll only the logo from the header container
Remove dojo class so all sites have title display at top on narrowest device width

No longer hide site-title if not of dojo class
No longer apply dojo class to site-title element if a dojo site

Note: Applied on Oct 15th, but forgot to commit after uploading to production
Further reduce overlapping from elements wrapping menu and logo
