Website message overhaul

[Andrei Alexandrescu]

Walter and I have been working on the website for a while. We want to 
crystallize a clear message of what the D programming language is.

Please take a look at http://d-programming-language.org/new/. The work 
is content-only (no significant changes in style, though collapsible 
examples and twitter news are a new style element).

Feedback is welcome.


Thanks,

Andrei
