1) Moved check_if_bin installed to run only once, when script first loaded (rather than every time it is called)
2) Changed executable path preferences per Bill's suggestions
dt.preferences.register("executable_paths", "align_image_stack",
dt.preferences.register("executable_paths", "enfuse",
dt.preferences.register("executable_paths", "exiftool",
3) Replaced custom block of code with df.create_unique_filename
4) Quoted paths in run commands for linux and MacOS (I still experience failures if I quote anything in the run command aside from the .exe path on windows)
5) Changed LUA API compatability check for 5.0.0 only
Tested on Windows and MacOS
