PHP Data sources

Problem/Motivation

Need to be able to create php code that generates data for the report engine. Some data elements, particularly in drupal need to be touched by php code.

Proposed resolution

Change all data providers so that they will look for a block_name.inc file instead of .sql file. If the .inc file is there instantiate a class by the same name and use a method to load the block xml based on data parameters passed to the block.
