entity.name.tag.localname.xml doesn't allow '.' char

The regular expression for matching the xml tag localname isn't correctly.

the '.' is allowed in the localname so the correct expression should be:

(</?)(?:([-_a-zA-Z0-9]+)((:)))?([-_a-zA-Z0-9:\.]+)

If have simply added the \. in the last group ... could you please add this in the XML.tmLanguage file THX ...

And: Sublime text is amazing! I will purchase a licence for Xmas for ME ;)
