Remove examples directories in AP and AR

Suggestion: The examples directory in actionpack/examples and
activerecord/examples contains pretty outdated code. I think there are
enough books and online resources available now that providing examples
in the source isn't needed anymore. What do you think, time to remove
it?

Wow. Revision 4 - pretty outdated indeed :-/

But I wouldn’t trade embedded documentation for books and blogs. This should be either deleted (in favor of documentation in class source) or updated for 1.2
