Python scripts are executed regardless of md5 hash check

[mchaaler]

Problem appears to lie in the following snippet in gen_single.py, in the generate_file_md method:

        if skip_and_return:
            # Return with 0 exec time and mem usage, and None thumbnail
            GalleryScriptResults(script=script, intro=intro, exec_time=0., memory=0., thumb=None)

Does not seem to return actually.

Simply adding a return statement in front of GalleryScriptResults() with "None thumbnail" as stated is not enough: it makes the call to script_results.thumb.exists() (in the _thumbnail_div method (in backreferences.py) raise the following exception:
AttributeError: 'NoneType' object has no attribute 'exists'

Suggestion would be to use the thumbnail pathname resolution process as implemented later in the same generate_file_md method.

Great description, thanks so much @mchaaler for taking the time ! Much clearer now.
