Several tweaks:
- StripeMask's comparison width is now 2 instead of 3 for blksize=16
- BlendOver default raised from 50 to 60
- Stripes default changed from "skip" to "blend" -- safer
- Output=over now displays stripes mask as yellow (and artifact mask as cyan)
- Debug now displays Diff and Stripe values, and 4 digits instead of 6 digits
- Works correctly in 16-bit mode while maintaining compatibility with AVS 2.6 (debug mode still doesn't work correctly in 16-bit)
