Old assets considered modified by git after each export

[danielchasehooper]

After doing a clean build on a new clone, or after changing a single asset in the sketch file, git considers all exported assets modified. Is there a way to avoid this? I noticed you reverted a diff algorithm, whats the story with that?

It doesn't appear possible to get "modified" timestamps per-slice. So the diffing I wrote compared MD5 hashes of the exported assets and only swapped out the ones that had changed. It got a bit messy and I wanted to ship, so I reverted. However, I would be happy to accept a PR in that vein.
