[Cin]New patch to alter file loading from command line

I thought it may be useful to alter default "Add filenames from command line to new track" behavior, and made new cmd line switch "-l", that can be set to anything, but useful values I tested are: 2 - load concatenated on one track (for jpegs) 6 - load as resources only Default is 1 as before Usage: bin/cin -l 6 ~/*.jpg or bin/cin -l 2 ~/*.jpg Please test if possible, and even merge if it doesn't add regressions
