#164: Filter values are trimmed before being used to filter results
Fixed Issue #168: Mage_Reports_Model_Resource_Product_Collection::addOrderedQty with flat catalog
#147: Add SKU column to sold product report grid
Add test for Mage_Eav_Model_Entity_SetupTest::createEntityTables
Make entity_id columns unsigned

Since the <value_table>.entity_id column has a foreign key constraint on
the <entity_table>.entity_id field they have to be declared identical,
that is an unsigned column can't have constrained on a signed column.
Enable developer mode for test
Remove transactions in eav/entity_setup::createEntityTables

Since Varien_Db_Adapter_Pdo_Mysql::_checkDdlTransaction forbids using
transactions for DDL statements (create, alter, drop, ...), we need to
remove the beginTransaction, commit and rollback method calls
surrounding the table creation execution.
