Add acronyms next to license names in "Licence selector"
List of acronyms (in this order):
Acronyms are widely used and not rarely you can see only acronyms, while the license name is hidden.
For example, Wikimedia Commons uses only acronyms below the photo and you get to see the full license name when you follow the link.
We already show acronyms in "Rights of use" to help the viewer understanding the license (for people who are used to acronyms). We should use them in the editor as well, to help the author in choosing the proper license.
