Add RandomLib to 3rdparty

RandomLib provides a variety of rng functions

Fix some issues with bounding boxes not being clipped correctly.
If the overlay would go past the image boundary, expand the image instead
of clipping.

AlgorithmCore Init function File to QString

…put to QStrings instead of Files to remove issues parenthessis and other issues

removed unused line of code

 made changes as requested to clean up code

removed temp variable

switched back to use temp variable

removing brackets

Previously, if the read block size was aligned with the end of the file,
the gallery would set done to false even if there were no remaining items.

Stream strongly assumes that done is set correctly.
