* Remove empty tags in addon.xml and add a disclaimer
* Update the description of the add-on in addon.xml
* Move icon.png into the "resources" folder to match Kodi guidelines (a
solid white background is added automatically by Kodi so the icon was
modified with a white background to avoid unexpected display and to
match Kodi guidelines)
* Improve the translation guidelines
* Add a missing dot in a localized string
