Checked every instance of testbase to see this dosnt break anything, also changed TESTBASE and TESTBASELIB, both were used incorrectly in places. added error_libdata() for library error messages that are everywhere. added object_data_is_libdata to test if the object and its data's are from a library. fixed 2 crashs in adding Curve points to a library object (remember to check, verify_ipocurve returns NULL!) made duplicating and making dupli's real for lib objects possible, disabled joining into lib armatures and meshes.
