As baggy theme was removed and material is the only remaining theme, we don't need a theme switched anymore.
So:
- move all `*.twig` files from the material theme folder to the root
- remove useless translations
When a user register itself AND the wallabag instance is configured to send a confirmation email, the user is disabled when the listener (which create the config) receive the event.
There were a check (don't know why) if the user is enabled we create the config. But the user is disabled when confirmation email is actived.
Using a listener, user config is now created when a user:
- is created from the command line
- register (with or without email confirmation)
- is created from the config panel
The `resetAction` was overriden to redirect user to the homepage instead of `fos_user_profile_show`.
Instead of copying the whole method we can simply use FOSUserEvents to handle that.
