Commenting and general code cleanup
ADD: performance to collage mode
If  image input is large enough like original photos montage reads
to memory all images before performing operations causing memory to
choke.
Using imagemagick resize on read we tell imagemagick to process each
image as its read and save to memory at a smaller size, leaving all
the work to CPU.

Performance enhancements
Artscript used identify to check for supported formats in file this
had the disadvange of taking a while when the file was big or when
you had to many. We now compare the file extension to a list making
artscript startup almost instant
If the file has no extension it will be processed using identify.

The new fucntion avoids using mapping functions, instead it just appends
the filename to the list.

NEW: add presets.config
NEW: add preset function to load user different defaults
