Subject: [PATCH 1/2] Brain transplants don't remove languages

Brains now retain languages from the mob they were removed from, rather than forgetting them. Languages are also retained when a brain is transplanted into a new body.

AIs, as well as cyborgs/robots/drones, will load languages from your currently-active preferences when they spawn (just like humanoid mobs do). Brains removed from cyborgs/robots/drones will retain their original languages regardless of the current module, and will no longer have access to binary, as they lack a binary communication device.

Brains in MMIs can now speak EAL if they know it, and additionally fixes #2832 - sign language will no longer be usable when lacking both hands. Also fixes silicons being told the wrong language prefix by the known languages window, as it was still showing ':', leading to much confusion among new borg players.

Known issues:
AIs who can use sign language can use it even without a holopad - I'm not sure how to have it check for that. This could be seen as a non-issue, as signs could conceivably be displayed on the AI's screen.

AIs signing over holopad will also have the language verbs overridden by the synth speech verbs (states/queries/declares). I'm pretty sure this has something to do with the already-existing bug that all languages can be understood by everyone when an AI speaks them over holopad.

Subject: [PATCH 2/2] Brain transplants, synthetics, and languages

Brains now retain languages from the mob they were removed from, rather than forgetting them. Languages are also retained when a brain is transplanted into a new body.

AIs, as well as cyborgs/robots/drones, will load languages from your currently-active preferences when they spawn (just like humanoid mobs do). Brains removed from cyborgs/robots/drones will retain their original languages regardless of the current module.

Brains in MMIs can now speak EAL if they know it, and additionally fixes #2832 - sign language will no longer be usable when lacking both hands. Also fixes silicons being told the wrong language prefix by the known languages window, as it was still showing ':', leading to much confusion among new borg players.

Known issues:
AIs who can use sign language can use it even without a holopad - I'm not sure how to have it check for that. This could be seen as a non-issue, as signs could conceivably be displayed on the AI's screen.

AIs signing over holopad will also have the language verbs overridden by the synth speech verbs (states/queries/declares). I'm pretty sure this has something to do with the already-existing bug that all languages can be understood by everyone when an AI speaks them over holopad.
