Many documentation examples can now be run online

[Andrei Alexandrescu via Digitalmars-d-announce]

Take a look e.g. at 
https://dlang.org/phobos-prerelease/std_algorithm_iteration.html. 
Examples now have "Edit" and "Run" buttons that allow you to play with 
them online and see what they output. Changes for the ddox version 
forthcoming.

Many thanks to Sebastian Wilzbach who took this to completion, and to 
Damian Ziemba for working on the online compiler code!
