Table alias in civireport for civicrm_case is a reserved word in SQL

The line in CRM/Report/Form.php that generates the table aliases produces the aliase "case" for table civicrm_case, but "case" is a reserved word in SQL.

It's this line in preprocess():
$this->_columns[$tableName]['alias'] = substr( $tableName, 8 );

Suggest adding a suffix that couldn't possibly conflict, i.e.
$this->_columns[$tableName]['alias'] = substr( $tableName, 8 ) . '_civireport';

Since in this situation the aliases are not for human readability or ease of typing, it's not too important that it be a simple alias.
