[whatwg] DOMTokenList feedback

I'm looking at the Gecko implementation of element.classList. I had a 
few comments about the spec.

1) http://html5.org/tools/web-apps-tracker?from=3253&to=3254 missed 
something. There is still a mention of alphabetical sort order in the 
beginning of section 2.8.3:
"element = tokenlist . item(index)
Returns the token with index index. The tokens are sorted alphabetically."

2) contains/add/remove/toggle should mention what happens if an empty 
string token is passed in the token argument. Looking at the DOM Core 
exceptions, throwing a SYNTAX_ERROR seems to be the best match in this 
case (if we consider an empty string as invalid):
"SYNTAX_ERR, introduced in DOM Level 2.
     If an invalid or illegal string is specified."

3) case sensitivity. Would be nice to address [1].
Note that the definition of uniqueness for .length and .item() will also 
need to be revisited if we want to handle classes in a case-insensitive 
way in quirks mode.
