Changed TESTBASE and TESTBASE_LIB to check the hidden flag

  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.
