Possible regression

I tested updating Gulp to 5.0.0 in #101. When installing the branch on our Site and Sandbox repos, I saw a possible regression in Sandbox when trying to run the copyAssets and copyImages compile scripts. The images would become corrupt and not be able to open properly. For whatever reason, this was not an issue on our Site repo.
