Added entries about SANE_CAP_ADVANCED in groups, a wip marker for sorted

sane-backends.html, and saneopts.??.po problem.  Removed backends from list of
inclusion beacuse of lack of response: v4l2, lhii, viceo (they stay in
PROJECTS). Removed snapscan from exported symbols bug list. Updated doxygen
list.
