More work on combining the inverse/converse builds

- Use `enabled` method for plugins
- Rename `converse-inverse.js` to `converse-fullscreen.js` and make it a
  core plugin.
- We're no longer making separate mobile and inverse builds

No longer a need to whitelist/blacklist plugins for inverse to work.

 ### UX/UI changes
