Chromecast, UPnP and AirPlay bridges updates

I've recently done updates of these plugins regarding codec supports, especially as part of my effort to bring streaming wav (aif maybe) support to LMS. I've pushed the updates on the stable version as the amount of permutations and combinations required for test is simply *way* above my capabilities so I need this community's help and understanding.

I won't be able to answer questions from users who have problems with these bridges which are related to installation or networking (firewall, docker, VM, multicast filtering, IGMP snooping ...). Please read the threads and rely on community's responses. Sending me a PM will not help nor will opening an issue on GitHub.

I also want to allocate my (limited) available time to the SqueezeESP/SqueezeAMP project as well as knowing better some of the LMS inner code.

Back to the codecs topic, to get the full updated list, you must erase the "codecs" line content in these plugin settings, wait a bit and refresh the page. The list will be updated with the most recent defaults. For UPnP bridge, if you want to try oggopus and oggflac, it's likely that your player will not report the proper mimetypes, so you'll have to add them to "Additional MimeTypes" - see documentation
