Anonymous rules fail when writeInputAttributes = true

[danikenan]

When I add any anon rule using the 'validation' extender I get an error if writeInputAttributes is also set to true.

The error occurs at:

"ctx.rule.toLowerCase() === attr.toLowerCase()" (line 548 in my version)

In prev version the rule (ruleName) was a Number (created by newId()) that had no toLowerCase.
In the latest version, it is simply undefined (also has no toLowerCase)....
