Book of Familiars

Major UI update:

• Texture now spans two pages rather than one.
• Added a search box to search for specific familiars.
• Added a stats display to show health, damage, movement speed, and how many items the entity has in storage if applicable.
• Added the default ability to store the fox, iron golem, snow golem, and strider.
• Updated the ownership check for horses so the camel is now storable by default.
• The book now opens on the page you closed it on rather than page one.
• Minor bug fixes.

Note: There will be a message in place of the stats display telling you to release and re-store your familiar to update the stats. The update is backwards compatible and your familiars will not be lost, but I recommend making a world backup before updating as a precaution.
