Closes #147

Stop git handling binary images files as text

When cloning the repository from scratch, 4 files are coming up as modified and attempting to run `checkout` to get to a clean state fails due to the rule in this file setting all files (`*`) to be processed by Git as `text` with automatic EOL processing. See the below for what happens:
