Always create and update pictures for SETs. (using subdirectories for images)

[krial]

YAMJ always upgrade ALL images for SETs ? I didn't change any images in movie folder.
If start YAMJ five times in a row it will create and copy ALL image files for sets 5 times.

all "forceXXXOverwrite" is set to false
only one "forceXXXOverwrite" sets true
mjb.forceIndexOverwrite=true

I'm using subdirectories for images.
mjb.dirHash=true
