Hot reloading doesn't seem to be working

[damienstanton]

This is the environment where I have the issue
macOS: 10.13.6
Gatsby: 1.1.58
Node: 10.9.0
npm: 6.4.1

Currently, saving src/slides.md recompiles the Gatsby project without errors, but the rendered slides do not change. I have to stop and restart the gatsby develop server to actually see any changes.

I have tried this in an incognito session and with cache disabled, and still have the problem.

Thanks for opening this! Hot reloading wasn't implemented yet, but should be working now with #7.
