fix to use foreign key and fix for SQLPParser bug
- Fixed to use "Foreign Key Attr References Table" to resolve referring types and translate table
- Added "Select Attr From Table" and similar clauses (can now select both Col and Attr)
- Updated SQLPSchemaRefExpTest1 and its test result (can now test directly with "./SQLPSchema < ./SQLPSchemaTests/SQLPSchemaRefExpTest1")
