Xenomorph Types

0.9.15
-added new xenomorph variant (swimmer), comes from fish and water mobs
-fixed worker drone variants not functioning in the hive
-fixed spitter queen not evolving
-fixed minor bugs with creative tabs
-updated the runner queen model so it doesn’t just look like a bigger version of its previous stage
-fixed xenos going crazy and getting distracted over mobs in a hive
-improved xeno ai, now doesn’t attack targets with gestation (only applies to mobs not players)
-xenos should now be aggressive towards non-vanilla entities
-hopefully fixed xenomorphs only tunnelling in one direction
-worker drones can now tunnel upwards
