Title: Disease Fix

* Fixes diseases using the data of the same reference, meaning disease data won't overwrite everything.
* Created a new reagent proc called on_new(). It will be called after a disease is created in add_reagent().
* Made vaccines copy the data they use, instead of referencing it.
