Homunculi configuration adjustments (#2092)

* Fixes #2073.
* Homunculi will no longer autoloot items by default.
* Homunculi will not Vaporize if their HP is below 80% when the master dies.
* The battle configuration homunculus_auto_vapor is now a percentage value to allow for further customization.
