Transferred Unit Health Synchronization

[VaelophisNyx]

Describe the feature
When transferring a unit to a teammate, if it has extra health over the base health of the unit but that health didn't come from veterancy, it is Removed entirely when transferred.

Expected behavior
Unit health should remain consistent across sharing, even if it has bonus health from non-vet. sources

Screenshots

Additional context
Context for a source of non-vet. bonus health is from the BrewLan modification set; despite being a mod I think a simple carry-over of health values would be a good idea in general.
(Asking the BL developer to do this on his end would be unfeasible most likely.)
