Red Lake and Hecatomb episodes were added on a permanent basis

Hey,

As many of you wanted to see PvE episodes permanently in the game and not as part of events, we added Red Lake and Hecatomb to the Coop folder on the Play screen. Expedition also moved there for consistency and not to clutter the Play screen.

Known issue: There is an incorrect "VERSUS" description on the tab inside the Coop folder.
