- use provided language and voices when playing on Mac
- fix hang in waiting for termination
- allow players to return a rank for a given tag,
which will allow for the best matching player to be chosen
depending on the context (eg, prioritize one player for videos,
one tts player for certain voices, etc)
This solves a few problems:
- We no longer need to write temporary files to disk, as files
passed on the command line with non-Latin text can be read by mplayer.
- We no longer need to deal with mplayer processes left around in
the background that have failed to terminate.
- We don't need to deal with the added complexity that comes with
polling mplayer's status output to determine when the file has finished
playing.
Also add seek_relative(), toggle_pause() and shutdown() as optional
methods on AVPlayer.
- the new API operates on AVTags so it can support TTS as well as
audio files
- added a simple "run for each file" implementation for mpv and mplayer.
- will need to test handling of unicode filenames on Windows
- the old mpv and mplayer code is currently not active
This simply wraps the field in extra text that the frontend will
deal with. Also added some helpers for extracting and stripping
audio and TTS tags from the rendered text.
Originally added in d7339d9a27b8abd65fbcf85f809fb0089046986f;
unfortunately the change message does not describe why. Images
are handled separately, so it should theoretically not be required,
and keeping it in leads to garbled text when people include %
on their cards.

If a user enables an old add-on and restarts immediately, it won't have
had a chance to update, and may raise errors that could have been
prevented if the user was running the latest version.
- web requests done on a background thread
- easier to use outside of the addon dialog
- gets max point version info from AnkiWeb, which we can use in
the future
