Check out the correct branch, then apply a patch to the UnrealEngine

unpatched versions of the files from git. Then, apply the patch to the clean code.
Note: don't git-commit the patch in UnrealEngine. Instead,
just let this script reapply this patch as necessary.
Unzip the unreal engine source, then apply a patch.
