[validate] range values are read incorrectly from markup

[etal]

When assigning ranges (and rangelength) through markup ,for example:

<input id="days" name="days" class="range required" type="text" range="[1,99]" />

the range is interpreted as a string and not an array leading to incorrect validation and inability to submit form.

patch to evaluate string if needed

Setting up validation via attributes is only supported for validation methods that expect strings or numbers as their parameters.

To setup range validation set min and max via attributes and use the autoCreateRanges option.
