- change aspect from a scaled int to a double so we can handle the wider

   range of aspect ratios we get from ffmpeg files.

 - add container_aspect to title struct (always zero except for DVDs
   when it's the aspect from the VTSI). To handle broken French DVDs,
   make HB complain & use the container aspect if it's different from
   the aspect computed from the video PAR.

 - fix ScanFunc's job template init so that it doesn't think the only
   legal aspect ratios are 16:9 & 4:3.

 - hb_reduce wouldn't reduce any fraction where both terms were equal and
   prime (e.g., 2/2, 3/3, 5/5, etc. would not become 1/1). Recoded it using
   Euclid's Algorithm so it always works and is faster.

+# if no file names are supplied a default set of inputs is used (see the

+# One line is printed for each HB run. It has the input dimensions,
+# output dimensions, crop, PAR, filename & options for the encode.

+# is indicated by "1:1" (to distinguish it from the explicit PAR "1/1").
