Makes bot that take damage return to a roboport for recharge and hopefully healing.
This mod has 2 settings.
The default (trade for health) uses the bots energy to restore it's health (1% energy for 1% health) until they are below the threshold where they go back for a recharge. In the other mode bots that fall below 60% health loose any energy above the threshold where they go back for a recharge.
The aim is for bots that take damage through e.g. fire to turn around and run away scared back to a roboport instead of committing suicide.
