Expand mutations support

[ushkinaz]

Currently, the guide doesn't seem to fully support visualizing or processing all the IV-specific properties for mutation categories.

We need to expand the mutation_category support to handle properties such as:

• iv_additional_mutations
• iv_additional_mutations_chance
• iv_fatigue
• iv_hunger
• iv_message
• iv_min_mutations
• iv_morale
• iv_morale_max
• iv_noise
• iv_pain
• iv_sleep
• iv_sleep_dur
• iv_sleep_message
• iv_sound
• iv_sound_id
• iv_sound_message
• iv_sound_variant
• iv_thirst
