Update pre-existing labels - fixes #430 closes gh-436

made assumption that any existing label which already has errorClass is
safe to update with a new message.
Revert back to checking for name attribute only when debug flag is set. Never throw an exception here. Fixes #621

Revert "Improve error handling when no element is missing its name attribute. Still need to set debug flag to see exception."

This reverts commit 22edeaf28f25352df46cb7fe992506d62f9a134d.
Remove clearing as numbers of `min`, `max` and `range` rules. Fixes #455. Closes gh-528.

These rules are fully suitable to check any comparable JavaScript objects such as strings or dates. Also clearing prevents HTML5 date input fields to work when these rules are coming from HTML.
