v0.8.1 - Wielding and description cache

• Added a 'wield' command and a couple of items that can be used as weapons throughout the Llama.
• Unarmed attack types for all described races.
• Wielded weapons are used in the combat descriptions generated by the LLM.
• To increase consistency, (and lessen inference time), I added a simple cache system, where, if the MUD's description of a room stays the same, ie same items, same characters, the description previously generated by the LLM will be used again. Much quicker when you traverse back and forth.
• Fixed a bug where some of the rooms descriptions weren't correct, making them not 'appear', and thus become hard to navigate to (the cellar being one of them).
