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.
- Install now extracts the redistributable archive to the game's `.lancommander` directory, under a directory matching the redist's ID
- Scripts are downloaded and saved to the same location
- BeforeStart, AfterStop, and NameChange scripts are now available for redistributables
- Change manifest reading/writing to use async
Media is now imported if its given an ID that doesn't exist in the database. This should almost never happen, but it's there if needed.
The login process for the launcher has been refactored to do some initialization steps on application start. This should include pulling down the profile avatar and validating connection on start.
Fixes#124
