Parse attributes according to the specification in AttrValue::from_u32.

Browse source 
This exposes another bug: "-0" failed to parse with str.parse(), and is now
successfully parsed into 0. However, input.size and textarea.{rows, cols} are
supposed to be "limited to only non-negative numbers greater than zero", so 0
is not actually supposed to be accepted.
