Previously, importing without autotagging just imported a bunch of Items. Now,
like the autotagging version, "import -A" creates albums based on the directory
hierarchy. The effect is exactly as if the user chose "use as-is" every time in
the interactive procedure. One side effect is that "import -A" can now only take
directories, where previously it could take single items on the command line. We
need a new solution for this kind of import in the future.
On terminals where the LANG environment variable didn't list UTF-8 as the
terminal's character encoding, the Python print statement throws an error when
it encounters a character that can't be encoded. So now we manually use the
"replace" policy for all output to the terminal.
