Add more transcoding options

* Redo max. bitrate options, add more bitrates in the lower end
* Remove SD/HD from the bitrate strings as the quality doesn't match up to what the backend selects (e.g. 1.3 Mbps definitely wasn't HD)
* Add option to force transcode mpeg2
* Add option to choose between h264 & h265 as a preferred codec for transcoding
* Add option to select preferred audio codec for transcoding/directstream
* Add option to select audio bitrate when transcoding (previously hardcoded to 384kbps for >2.0ch & 192kbps for <=2.0ch)
* Add option to select max audio channels (e.g. for server-side downmix)
* Add option to hide embedded/internal & picture-based subtitles in the track selection dialog
