Change the window titlebar to show the joined server

[VasilisThePikachu]

About the PR

The games window title will now update with the hostname of the server. Updates with hostname changes, and can optionally be disabled by the server with the game.hostname_in_titlebar cvar (in case the server updates the manifest.yml to show the server name instead and does not have other server to warent having their server name on the title bar)

Why / Balance

Makes the life of admins who have multiple game server joined easier by being able to find each server from the titlebar

Makes it easier for players to identify what server they joined if they forgot.

Looks cool.
