Internet radio browser GUI for music/video streams from various directory services.

⌈⌋ ⎇ branch:  streamtuner2


Check-in [5588baf6dd]

Overview
Comment:Implement custom HTML .entitiy_decode, because SAX didn't honor any HTML; and HTMLParser would require customized/compat2and3 imports.

Colorize channel labels if #color: is specified in any plugins.

And provide @use_rx decorator to alternate between regex/pyquery extractors.
