Butterfly v18n Update!

This update was primarily to add a unique channel to the butterfly, and a button on the Control HUD just for controlling the butterfly.  While I was at it I made a handful of other edits and quality of life changes along with a few memory fixes to make it less likely that they fail.  However, I've also added a special variable within a subscript to store vital Butterfly information, and a developer button to hard-reset the pet using this stored data.  This should make it quick and easy for me to jump-start a "stuck" pet in the future.

• The Sorcerer and Elemental classes have been added, along with the supporting particle-effect chains to unlock them.
• The butterfly's sub-version letter "n" has been added next to the version number to make it easier to identify pets that need to be updated.
• Support for a butterfly cocoon/chrysalis collector has been added.
• Swirl and No Swirl on the Control HUD cause the butterfly's wing animation to start and stop.

Life and Food, two values that have been cosmetic for a long time now, are no longer displayed in the hovertext.   Pets are so stuffed with food that I haven't bothered actually keeping track of Food% for quite some time.  The number was hard-locked to 99.9% the whole time.  F+ comes from too many sources bother making the pets actually go out and search for food -- most of them are never hungry anymore.  Likewise, Life% hasn't been a problem after spiders and their linked sensors were removed.  Priests and other Life% granting classes are likely going to be given a new, unique purpose when I get a chance =)
