[FIX] Fixes for xenomorphs

[ErdGinalD]

What Does This PR Do

• Xenos now bleed with lime blood color, instead of red.
• Xenos now doesnt have neutral fraction, as any other biohazard(blod, spooder, demons). Now its only alien.

Why It's Good For The Game

Red blood is not good for immersion Neutral xenos are not exist in this world

Images of changes

Neutral xenos - the only biohazard you have. This is clearly an oversight

Before update:

After fix:

Testing

Spawn xeno, kill him. drag him, see the green blood as expected. Spawn goliath, he attack xenos. Kill him, revive him with lazarus, now he is neutral but still attack xenos, as he do with spiders or blobs.
