merge r1162 from branch-1_6 into trunk

fix: calendar prev/next links not working properly when 'any' (All/Tout)
was selected

fix: calendar 'any' (All/Tout) not shown on for the day selection
(last calendar level) - it was meaningless

fix: calendar image ordering is by date descending for large periods (no year
selected) or ascending for small periods (week,month...)
