chickeneer e9ca4fcd65 Change valid name checking to a configurable predicate #382 
I see the value in allowing acf users to disable the valid name check.
I think others may want to go a step further and create their own
valid name verification. Those that want to truly accept all names can simply
do `CommandManager#setValidNamePredicate(name -> true)` with the new API.
Another solution I considered was having users override the isValidName method
on their CommandManager, but this functionality seemed more friendly.
