2.1.7 (2015-04-26)
- Experimental support for drag and drop, which allows playback,
  importing, or exporting stations from/to files.
- Configuration dialog became more clearly arranged by separating
  channels and feature plugins.
- More manual examples on recording configuration added.
- Several enhancements to playlist conversion, support for .desktop
  links, better heuristics, and working url+title extraction.
- All MOD files use generic audio/mod+zip MIME type.
- Use new and distinct /tmp/streamtuner2/ directory for cache+export.
- Implemented hashing for cached m3u/pls files.
- Support "feeds" stream in Jamendo, more complete Ogg Vorbis support
  and JAMJSON extraction instead of using old v2 API.
- Initial startup and application state restoration became more robust,
  active category is tracked more dynamically.
- Some internal simplifications and code cleanup (logging simplified,
  more uikit wrappers for Gtk3, removed outdated PIL workaround,
  cleanup up remnant module descriptions).
- Statusbar is just a plain text label, automatically emptied.
- Disable partial stream refreshing, and threading per --nt flag
  or config option, because Gtk3 support is still flaky. Let gtk_idle
  callbacks run in order through an internal precedence spool.
- Browser invocations corrected.
- Crash in cache search fixed.
- PYZ building now supported by xpm and Packfile for custom adaptions.
