Adds siik'tau and a bit more (#4947)

This pr adds siik'tau, as proposed here: https://forums.aurorastation.org/viewtopic.php?f=78&t=11259
A language that humans, skrell and tajara can select.

Also, tweaks how skrell handles language at the request of the skrell lore person and cleans up a tiny bit of the species language related vars.
