Fixing right to left (short: RTL) support for respective RTL languages
by adding auto-detection for the user content's directionality based on
the text's language.
Fixes#612
This adds a new editor template that strips away most of the
customization features in the default editor and includes only:
- publishing
- editing
- viewing word count
It also restricts publishing to a user's first collection, so it's
optimized for instances that only allow users to have a single
collection and don't use Drafts.
