Option to ignore particular fields

[nfplee]

I'm looking at using this library. One feature I believe is missing, is the ability to ignore particular fields. For example, using jquery.validate I would've been able to say:

$.validator.setDefaults({
    ignore: ':hidden:not(.validate-hidden)'
});

This allows me to conditionally specify which hidden fields I may validate. This can be expanded for additional cases too (such as the option of not validating disabled fields).

This seems pretty straightforward:

• Default value is ":hidden"
• Skip calling the validator
• Excluded when finding validatable elements
  • Noting we don't support contenteditable
• Exclude when finding validation target
