Let validate return a string as error message

[pke]

Currently it seems like validate is the only rule that can not return a string to indicate its error message.

How about changing this to

validate: (value) => value === 42 0 ? "Can't be 42" : true

pretty sure validate can return string

You are right! None of the examples does it though, but a peek into the source code helped to clear this up.

pretty sure we do, there is a radio button to toggle the error message at register
