Reorganization of /istack command, bugfix and user requested feature update.
1) Reworked the way the /istack prot command works, now you'll see a more condensed list with some links for showing/hiding other protections. I also created a category for lesser used / user requested features to as they aren't generally used by everyone. This keeps the /istack prot command page a bit more managable imo.
2) Fixed a bug with villager cure chance, it now accurately works if set down to a lower number say 2%, and if set to 0% will NEVER allow a villager to transform.
3) Added a user requested feature to change a spawner type to a pig spawner when broken. This is useful if you have a silk spawner plugin on your server but odd spawner types you don't want players to mine. EG if you had a shulker spawner, in the end, and didn't want players to silk touch it and bring it into the regular survival world.
