Background Downloads

[Efruit]

Couple of scenarios for this one:

• Content is connected to a server that receives an update during the round. Robust should provide a mechanism to inform the launcher that a new version is available and will be used soon. In this case, the Launcher should throttle the download so as to avoid messing with the game connection.
• The Launcher boots up and scans the Favorite servers. If any of the servers are running games or engine versions that aren't currently cached, the launcher should preemptively fetch them.
