MobIdLookupTable.yml (the pseudo yaml file). Make sure to delete any
existing yaml MobIdLookupTable that might still exist as an old version;
i haven't put in any version checking yet.

This reverts commit 93ef97f30f138641a07189fe4cf951eda33ac642.
Added two predefined enums specific to plugin: mobtype and potioneffect.
These are to be used with the yaml config file for completely dynamic
mob creation that takes effect with a simple reload of plugin!
