The placeholder= tag now follows a new format: placeholder= <placeholders> instead of placeholder= <panel name> <placeholders>
Adds cpi= <custom item> a material tag that can take panel custom items and use them.
added %cp-setdata-dataName,dataValue% to edit data values via placeholder.
added%cp-mathdata-dataName,dataValue% to edit number data values via placeholder.
For example, adding these placeholders in the name section of an item will execute it every time the panel refreshes, with no changes to the name visually.
refresh-panels= <number> that is in the config.yml for controlling panel refresh speeds can now be added into panels to add a different value for that panel only.
panel custom items can now contain hasvalue, hasperm, etc inside of them.
