Autobuild doesn’t know when to commit zips

[andylolz]

@codeclubrobot can generate zips of resources, but he doesn’t know when to commit them.

@codeclubrobot does the following:

• clones the static projects repo (UK or world)
• deletes everything
• rebuilds everything
• commits everything (git add --all)

This is dumb and slow, but effective! git does all the hard work (figuring out what has changed). The only problem is zip files, because git thinks two zip files containing an identical set of files are different.

zip -u does fairly well at solving this.
