Allow applications to change activity text through DIscord RPC

When using Discord's RPC feature, we are able to set things like the title, description, elapsed time, etc... for our application, but when the activity is shown on Discord, the header text will always say "PLAYING A GAME", after which our custom data is shown.

If we look at the activity of Spotify, that text will instead say "LISTENING TO SPOTIFY", indicating that the text is changeable.

Why are we not able to change this text through RPC? When developing applications that are not games, the end result of this implementation doesn't appear as polished because of this.

The spotify one is localisable, just like the default "playing a game". In this proposal, apps would need to provide localised strings themselves.

I don't think that presents a problem, since this feature wouldn't have to be something that you're required to use. If a developer so chooses, they could keep the standard (current) behavior, meaning all the existing products wouldn't be affected at all, but for those who wish to go the extra mile, this option would be available.

Applications wouldn't need to provide this, as activity texts aren't required to be (and can't) localised either.
