Ported GildedRose to Oracle PL/SQL

Emily,
again I am happy to offer you another port of Gilded Rose. I will use it with a team of DB developers and have ported it to PL/SQL. I also added an empty testcase for utPLSQL, one of the two available testing frameworks for PL/SQL.

Also I noticed that I forgot the texttest fixture for PHP, so I added it as well.
Take care.
