* OPT: Some optimizations again in memory allocator, object releasing routine, arithmetic operators, class variable reader, line-by-line stream reader, class symbol sort routine. * BUG: Using constant strings inside variant, like database drivers, works correctly again and does not crash the interpreter anymore. git-svn-id: svn://localhost/gambas/trunk@2996 867c0c6c-44f3-4631-809d-bfa615b0a4ec
