New look & feel for std.algorithm

[Andrej Mitrovic]

Also, on some pages there's still a Digg button. Other than the fact
that Digg is practically dead (everybody who knows about Digg seems to
admit this from what I can tell), I don't see a reason why it's there
on some pages while not on the others, e.g.:

http://d-programming-language.org/hijack.html <- digg button
http://d-programming-language.org/migrate-to-shared.html <- no digg button

I say we just kill it.
