Integration with BestSource #6

Now that BestSource has hinting of RFF flags via FrameProps, VIVTC could make use of this information to improve it's fieldmatching & decimation accuracy.

Exactly when would it help? Mostly soft pulldown material? Speedup due to knowing when matching is pointless (same field tried for multiple matches)?

From my observations there is quite a bit of "mixed scan type" anime DVDs ranging from 30% to 70% soft pulldown. VIVTC's decisions are far from perfect and I imagine making use of such flags would help significantly since it at least ensures those portions are matched/decimated correctly.
