combine isEmail and allowEmpty

[ir-fuel]

It seems that I cannot use allowEmpty in the validate attribute.

What I would like to do is validate a field to be either a valid email address or empty. I don't seem to be able to do this? Am I correct or am I missing a simple way of doing this?

            <ValidatedInput
              id="profile-companyMail"
              name="companyMail"
              type="email"
              placeholder="Email"
              validate="isEmail"
              errorHelp="Incorrect Email"
            />

I would like to be able to put something like validate="allowEmpty,isEmail"

Thanks for helping me out!

Please see pull request #53 .
The syntax will need to change as the assumption is that everything is an "and" condition at the moment. Extending the framework to handle "isEmpty" is fairly straight forward but the conditional processing parsing is a little harder and needs some more work.

Comments and suggestions are welcome on PR #53
