loathingKernel 2ef70b8eb4 InstallQueueItemModel: Refactor to add an expiration date to the download
While not sure if it is required, add an expiration date to the prepared
download 30 minutes after it was prepared. If a download has been in the
queue for more than 30 minutes, the download will be prepared again silently
before starting.

Return only the `InstallOptionsModel` in the result of the download thread
to avoid the potential mistake of re-using it. This required for the tray
notification signal to operate on the `app_name` instead of the `app_title`.
As a result, the notification slot was moved into the TrayIcon class for
better encapsulation.
