Fix Various Language Trait Issues (#1441)

# Description

Fixes some various issues with language related traits, such as Mimes
being able to take the Mute trait for "Free points", Foreigner being
able to be combined with Mute for "Free Points", etc. Foreigner being
able to be taken by Mimes for "Free Points". Also stuff like the "Rare"
languages giving you points instead of costing points, Sign Language
being the "Best Language" because its mechanically better and free, so
now it costs points, etc.

# Changelog

:cl:
- tweak: Mimes can no longer take the Muted or Foreigner traits. 
- tweak: "Rare" languages like Sinta'Azaziba, Valyrian Standard, now
cost points instead of giving points.
- tweak: Sign Language now costs points.
