Michael Fabian 'Xaymar' Dirks cd5acd42f4 obs-source-factory: Add settings migration code
Previously sources had to manually implement migration code, which resulted in unresolvable regression issues due to the lack of version and commit tagging. With the new migration code, all sources automatically have this version and commit tagging at all times, and as such can now have a temporary regression fixed without the user needing to change any values manually.
