add title changing to router

[sarimash]

Description

Names can be changed if desired; I used 'My Profile' for the profile to distinguish from other players' but did not use My on 'Inventory' or 'Collections' because the player would not be viewing other players'.

If the data field is populated, we use the data field + " | AtEoAT" otherwise we default to the game's name, as in the home page:

Also noticed that the original default on the index page was using the wrong name for the game, so threw in a quick fix for that.
