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.
