Added style to class "textile" divs which limits width to 50em, helps break up insanely wide comments.
Added the ability to run advanced searches from external URL.
Added (presently undocumented) parameter to observation advanced search
to have it include location notes in what it searches for when you give
it a location name.
name_lister requires successful user, and tested fixed. (from master jul 6)
Made some tweaks to parsing of lat/longs (from Jul 27 and Aug 16 on master).
Code is now sort of rebased with respect to master as of August 18.
(Which is to say I applied the Apr 23, May 4, Jul 6, Jul 27 and Aug 16 patches
from master to the end of this branch.  Actual rebasing looked too difficult.)
