Cleanup some commented out crap
When EmptyVanillaSpawnlist is enabled, vanilla spawn list entries are still imported.
JAS now searches all vanilla entry types irrelevent to the type of Entity JAS detects.
Clear vanilla spawnlists is enabled by default, still toggleable by configuration.
All Entities shouldSpawn properties default to true.
Spawning still does not occur if the entity type is NONE or wieght <= 0.
Merge branch 'feature/useability' into dev0.9
Closes #52
