✨ Added Source as the new default theme

refs TryGhost/Product#3510

- Added `TryGhost/Source` as a submodule in `ghost/core/content/themes` so `Source` will ship with Ghost (along with Casper)
- With this change, new installs will use `Source` as the default theme. Existing sites will have `Source` installed, but not activated, as this is a large change and we don't want to drastically change existing sites without warning. Users can upgrade to use `Source` simply by clicking 'Activate' in design settings.
- Updated protections to prevent users from uploading their own conflicting version of `Source`

+## Updating the Source theme fixture
+The source fixture is a partial copy of the content/themes/source folder.
+It should not include any files that aren't needed to run the theme.
+
+To update it:
+
+1. Ensure your `content/themes/source` folder is on the latest released version e.g.
+
+- Run `yarn main`
+- `cd content/themes/source`
+- `git log -20` - find the latest tag
+- `git checkout vx.y.z` - checkout the latest tag
+
+2. Ensure you are in side this folder (the fixtures/themes directory), remove source entirely and then copy it across fresh:
+
+- `cd tests/utils/fixtures/themes`
+- `rm -rf source`
+- `rsync -rv --exclude '.git*' --exclude 'assets/css*' --exclude 'assets/js*' --exclude 'gulpfile.js' --exclude 'yarn.lock' --exclude 'README.md' ../../../../content/themes/source .`
+
 ### Modifying theme fixtures
 When a new rule is introduced in gscan one of these fixture files might break and you'll have to update a "zip" which isn't as easy as opening a text editor... It could become that one day but for now here are some commands to help out with the edit process
