Fixes #144: behavior of add_copy mode during add.

- correctly handles add_copy mode and configuration,
- add option top force 'copy' mode (since the default had been changed
in between from 'copy' to 'move' this is now needed),
- fixes assumption in one test that the default is 'copy' (in other
words the test was broken and ensuring that the functionality was broken
too.),
- do not try to delete the source when it is an URL.
