Added a draft pinto tutorial.

Gabor-

Here's a copy of the Pinto tutorial that I wrote.  Much of it comes from Pinto::Manual::Tutorial.  Currently, the format is just plain text.  So you may want to convert it to markup before having your translators work on it.

It would be great if you could publish this before the funding campaign ends on May 7.  But please do not publish before May 4 -- pragmaticperl.com has the rights to the first publication.  But you could start having the translators work on it now.

Thanks so much for all you do in the Perl community.  You are part of what makes this place special.  Keep up the good work!
