Image files with DOTs in the filename in SS4.2.1 - temporary fix until next release is out

Super important for SS 4.2.1 current version if you’re trying to move over an SS3 asset folder and some files have DOTs in the filename (not something I like doing but if you inherited filenames with that and you’d left them then you’ll hit this bug).

Go here… and manually patch your copy of this file as a temporary Tip until the next update comes out.
