Incorrectly accepts "anon tag without a value" when the tag has children

[Abscissa]

This is dedicated ticket for "case 1" in Issue #9:

If brace appears on it's own line, SDLang-D silently ignores everything inside the curly-braces and does not throw an error:

parent
{
  child1
  child2
}

It should throw an error (like the Java implementation does) because anonymous tags are supposed to require at least one value. Quoting the language guide:

Note: Anonymous tags must have at least one value
Anonymous tags must have one or more values. They cannot contain only attributes. This design decision was taken to avoid confusion between a tag with a single value and an anonymous tag containing only one attribute.

Not allowed: An anonymous tag with a single attribute (and no values)...

size=5

...because it could easily be confused with a tag having a single value

size 5

@marler8997: You may want to know: The fix for this involved a slight change to the grammar in the parser's comments. Specifically, to the <Root> and <TagTerminator> nonterminals.

Thanks for letting me know and thanks for fixing these issues so quickly. Daniel was on vacation last week so hopefully he gets back to me today. I have a few pending emails to him about some of the cases from issue 9 (and the whitespace issues for namespaces and attributes). I'll let you know what I find out.
