tagName property is always undefined

[blackmambahk]

there is a problem with parse.js line 67:

byTag[current.tagName] = current;

current.tagName is always undefined.

In parse-tag.js line 33 the property 'name' is set not tagName as referenced above:
res.name = match;

I think it should be 'tagName' as 'name' can conflict with an attribute 'name' in an Input tag for example..

Also 'byTag' seems to be unused so could be removed.
