Some dev servers like next.js use Gzip which breaks our content
injection so we avoid getting gzipped response when we need to do the
shim injection.

Fixes #163

Whenever Dyad does a commit from a proposal, it will automatically amend
the commit with outside changes (e.g. made outside of Dyad).

This helps avoid a lot of user confusion, e.g.
https://github.com/dyad-sh/dyad/issues/187

https://www.reddit.com/r/dyadbuilders/comments/1kjysc0/error_pushing_images/

Edge cases:
If a user adds a file outside of Dyad, and then they hit retry, it will
revert these outside changes, but it's still technically in the version
history, so I think it's OK. This should also be a pretty unusual
situation.

- [x] make sure it works with older apps
- [x] what about cache / reuse? - maybe use a bigger range of ports??
