Running from command line skipping first png in set

[mildfuzz]

I have a set of 20 png's to add to a spritesheet.

Running spritesheet-js -f easel.js --trim *.png create a sheet and json document as expected, but does not add the first image in the set (listed alphabetically).

It is repeatable in that renaming the first image causes a different image to be skipped.

For now I have added a superfluous image 1.png which is accounting for the error, but would be good to be fixed
