Conflicts:
- `README.md`:
Upstream README has been changed, but we have a completely different one.
Kept our `README.md`.
- `lib/sanitize_ext/sanitize_config.rb`:
Upstream added support for more incoming HTML tags (a large subset of what
glitch-soc accepts).
Change the code style to match upstream's but otherwise do not change our
code.
- `spec/lib/sanitize_config_spec.rb`:
Upstream added support for more incoming HTML tags (a large subset of what
glitch-soc accepts).
Kept our version, since the tests are mostly glitch-soc's, except for cases
which are purposefuly different.
