Shield stealing to restore your own health as well as stealing another object's entire ShieldType both seem to be working correctly. I was able to use:

• non-respawning zero initial health shields were respawned and filled up by shield.steal
• shields can be successfully stolen based on their type, and this works between technotypes (infantry can steal tank shields, buildings can steal aircraft shields, etc.)
• shields not specified to be stolen cannot be stolen

I wonder if the naming for turning on warhead-based stealing could be a bit better. This is just personal opinion, but perhaps Shield.Steal= could perhaps be Shield.Assimilate= to match second tag (Shield.Assimilate.Rate). Or Shield.Assimilate.Rate renamed to be Shield.Steal.Rate=?

EDIT: If you test this PR, make sure to check the changed Documentation as the updated tags are found there and not in the initial comment.
