Non-Vanilla MedBots heal using vanilla behaviour (Up to 100, instead of maximum health)

[theastropath]

In Revision, the medbots (and likely other healing items) continue to heal you up to 100 health per body part instead of respecting the configured maximum health.

Rather than using the players HealPlayer logic, we could build that into the replaced MedBot for non-vanilla and use that instead, allowing the bot to respect the health maximums.

Or, of course, we could implement a new player class (#187 ) and fix it there.

Fixed for Revision with a new player class in f47b37f
