- Add a minimalistic text editor (leafpad) and a filemanager (pcmanfm)
  as soft dependencies. These are the bare minimum to have a usable system.

- Alignment with openSUSE packaging guidelines
  * Use %find_lang
  had to use --all-name otherwise translations were not matched
  and package ended up with installed but unpackaged files
