Switched the library importing in the launcher to work based on a queue. As a new game is added to the queue, it should find any related data and also add it to the queue. This should result in an easier to maintain importer while reducing the load on the launcher's DAL. This may result in more RAM usage while importing. Local manifests have also been refactored to match manifests in import/export LCX files, removing the old manifest format. This is a large breaking change that will probably break existing game installations. A migration will probably have to be created.
Changes to game launching:
- Games can now be launched using the SDK
- Games can be stopped by the SDK
- Running games are tracked by the SDK
- Game state in play buttons are now tracked by polling SDK game service
- Library service no longer controls any launching/stopping/tracking
- Actions now are keyed in the manifest
- Game launching occurs in a GameExecutionContext
- Game launching variables have been consolidated
