refs #8235
Usage:
- for existing development setups: `grunt symlink` (will create the pre-commit symlink)
- for fresh development setups: `npm run init` (symlinking happens as part of the typical set up)
- ✨ Added pre-commit hook to handle submodules
- Checks to see if there are any submodules about to be committed
- Output matches closely to `git st` to make it easy to read
- Requires interaction from the committer to accept that this really should be committed
- ✨ Use grunt symlink to register githooks
- Grunt symlink will make a link to the pre-commit hook
- It ONLY does this if there isn't already a pre-commit hook, so won't overwrite anything
- It does this as part of npm run init, not grunt init, because a release repo would NEVER want this
- This is a dev tool, that configures the repo for development
