move v4l_multibuffer and v4l_captures_per_frame from Config to Monitor and Local Camera
change the way v4l_multi_buffer is loaded.  Since t's a bool, it theoretically is 1 byte, so can't use atoi
fix
ensure captures_per_frame >0
add missing lang entries for MultiBuffer and CapturesPerFrame
add V4L
Merge branch 'v4l_to_monitor'
add the db updates for the V4L changes
