Allow attributes to have a value of zero (eg min='0') #1029

I've found that HTML rule attributes that have a value of 0 are not applied, for example, min="0". If min="0" is specified, the user could still enter -1 in the <input> field.

This is because in attributeRules() there is a truthy test on the attribute's value before the rule is applied, so anything equal to 0 will be ignored.

To fix this, we also check for value === 0. If so, the rule is applied.

Tests were added to validate this.

This could be combined with the previous conditional

if ( value || value === 0) )

the typeof can probably be skipped since you are using a strict comparison

Good point, PR updated

Any other feedback? Pretty simple PR with unit test coverage of the changes.
