Forgot to list all changes in the latest commit, so here goes:

Allow multiple calls of <Use/> for multiple-use syringes or something
Adds hasstatustag and hastag conditionals, where hastag checks for item tags and hasstatustag checks for active delay/duration status effects w/ matching tags. It's also possible to check for NOT tag e.g. hastag="! morbusine,uranium", which will only be true if there's no morbusine or uranium in the "bloodstream".
Renamed "Amanitin" to "Sufforin" and slightly buffed it
Added "name" and "speciesname" conditionals
Makes bandages heal you slightly if your health is > 50
Adds "Morbusanide", which is a Morbusine antidote.
Calyxanide can hurt NPC husks now
Adds <Cancel all="false"/> which only takes effect if there's a conditional for specified status tags.
