Improved Podcast

Clearer confirmations on the Podcast recording review page

Removing a Soundboard event or resetting a mix now uses Magpie's own confirmation dialog and says exactly what will happen.

The recording review page used the browser's plain confirmation popup when removing a Soundboard event or resetting a take's mix. Both now use Magpie's styled confirmation dialog. Removing a Soundboard event names the event being removed. Resetting a mix states how many tracks will have their volume and mute settings returned to default, and its button reads Reset all tracks.
