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.
This does a very basic job of bundling a PowerShell runtime into the SDK. Previously, scripts had been run by spawning a separate PowerShell process and feeding the script into it. This was nothing better than a hack and meant that PowerShell had to be separately installed on the machine it's executing on. This should open up the opportunity for scripts to run on other platforms.
There's still some things that need to be figured out. Some sort of console output as well as a debugging mode would be highly beneficial for those that wish to actively develop scripts for their games.
