Primarily intended to make it easier for third-party applications
(mainly Heroic) to handle launch options on their own by simply
taking the necessary information from legendary and ignoring
user-defined stuff.
Also useful for debugging.
- Games that didn't already have cloud saves weren't synced
- Games that didn't have local saves didn't behave correctly
- Games that only had local saves also didn't work correctly
Ownership verification tokens appear to be part of EPIC's DRM scheme,
they're basically just a JSON file with a token in it that's downloaded
from their API before launching.
This fixes launching games such as Just Cause 4.
