Version 0.91 released

A boring version containing fixes mostly. Also finished audio and made all trolls resistant to cold.

– [design] Added third exotic food (somehow I forgotten to add it earlier so the cook quest was impossible to finish).

– [misc] All trolls are resistant to cold now (it’s more consistent and intuitive).

– Finished audio (replaced remaining placeholder sounds with proper ones).

– [fix] Heavy Forge Armor was giving immunity instead of resistance.
– [fix] Magic doors in Ogre forts were unlockable.
– [fix] Description of Character button was showing wrong default hotkey.
– [fix] Healer’s Regeneration spell was not working under certain conditions.
– [fix] Arcane Mastery talent not working.
