New Logo, Misc. Cosmetic Changes

Made a few changes:

Patched in the ability to add arbitrary classes onto a result in the
listing.  This is used to highlight jobs newer than one hour as being
"new".

Added a province drop-down to the results listing.  Doesn't actually do
anything, but I think I have the appearance the way it ought to be.

Added a "Back to Search Results" link under the logo to all pages that
aren't the search listings.

Fiddled with the sizing of the logo and associated text.  Wound up
splitting them into two images for finer-grained control.

Added Google Analytics.

Changed some linger colour/style problems from the CivicInfo Mobile Site
(blues etc. where they didn't belong).

Changed the time format to be more compact.
