[radiofrance] handle new francebleu website, retrieve the good player url when default player is the video player

FIP now uses the same website as most Radio France radios.
As a consequence, it is able to support CapVideo.

There are a few differences between FIP and the other radios, but this
still allowed for less code, and the code should be more robust for
every radio.

Works with France Inter and France Culture

* Support for France Inter and Le Mouv', and many new radios.
* For some radios only, the current emission is fetched. Previously it was
 wrong for all two of them.
* New icon.
* Fix typo in LICENSE.
* Fix code style.
* Use fillobj() instead of duplicate code.
* Since there is not much left of the originals, I made myself the maintainer.
