Slave bot v2 updates

This adds new updates to the Slave Bot export functionality by @NGBot and myself (almost entirely @NGBot), including:

• Better intro messages
• Better support for mindbroken slaves
• More hair detail (including hair color and length)
• Better awareness of blind and mute characteristics
• Context for slave relationships and rivalries (not yet with player)
• Better world context
• First version of an integrated lorebook
• More detail about the player/speaker

@NGBot's original v2 update file can be found here: #4969 (comment 368036)

@Pregmodder I've tested this myself and it works well, so it should be good to go as is.
