Changes since 1.36.7

Fix js error in montage review when using scaled mode. Fixes [#3351]
French translation updates
fixes to packetqueue locking which should reduce RAM consumption in certain cases.
Don't crash in rstp server when unable to create source
Fixed a bug in Image::Buffer that would return the wrong location in the image if the image had > 1 channels (and if the request were for x > 0)
remove useless commit in zmfilter.pl causing logged warnings
fix width=0px causing empty looking montage
Handle when SERVER['HTTP_HOST'] is not set
allow values != -1 in setting Brightness, Contrast, etc in zmu
