Marco Burstein ba46dc83c6 notifications: Add a setting for changing the notification sound. ... Also, add a new notification sound, "ding". It comes from https://freesound.org, where the original Zulip notification sound comes from as well. In the future, new sounds can be added by adding audio files to the `static/audio/notification_sounds` directory. Tweaked significantly by tabbott: * Avoided removing static/audio/zulip.ogg, because that file is checked for by old versions of the desktop app. * Added a views check for the sound being valid + tests. * Added additional tests. * Restructured the test_events test to be cleaner. * Removed check_bool_or_string. * Increased max length of notification_sound. * Provide available_notification_sounds in events data set if global notifications settings are requested. Fixes #8051.		2018-12-09 21:25:30 -08:00
