Billy - UNBEATABLE PROPER RHYTHM Ult Replacer

Adds PROPER RHYTHM (ALL THERE IS TO IT) from hit rhythm game UNBEATABLE over top of punkgoat_tether_cast.vsnd_c and mutes punkgoat_tether_timer.vsnd_c.

To manually install, rename the vpk file to pak##_dir.vpk where ## is any set of numbers not already in use and copy the file to Deadlock/game/citadel/addons/. To uninstall, rename the file to something else or remove it from the addons directory.

For my dear friend Anne :)
