Official D Grammar

[Brian Schott]

Status update:

My parser is at a point where it can parse all of phobos (well, 
excluding c-style array declarations, which I'm convinced are 
broken and should be removed from the language).

I've been updating the grammar definition as I worked on the 
parser. An HTML version is available for download here:

Lexer, parser, and AST code is available here:

Bug reports and pull requests are welcome.
