Rename method "validate()" to "isValid()"

The method has been renamed some time ago, but I haven't updated the
documentation to cause less confusion. Now that I want to start updating
the documentation, I switched the default branch on GitHub to the latest
stable version, so I assume there will be less confusion in the
documentation, and I can start updating the docs for the next version.

 ## Validator reuse
