Update to 1.0.0
    
    Also do various cleanups:
    - fix typo in License
    - update BuildRequires (some deps are no longer needed, one was missing)
    - explicitly remove unused code from 3rdparty
    - clean up references to bundled taglib and utf8-cpp (no longer bundled
      upstream, nor in the Fedora package)
    - remove explicit adding of -fPIC to CXXFLAGS (it already gets there
      naturally somehow)
    - drop patch that no longer applies (and doesn't seem to be relevant
      anymore)
    - add BR on fftw3 to enable Moodbar support
