Bugfix: using --import could fail when finding dated folders using a different delimiter
Bugfix: using --import could fail when finding dated folders using a different delimiter

If the destination folder contained any folders prefixed with %Y_%m_%d,
and you used a different date delimiter, an exception would be raised.

  File "exportiphoto.py", line 454, in build_import_album_dirs
    folder_date = datetime.strptime(m.group(1), "%Y" + delim + "%m" +
delim + "%d")
  File "/usr/lib/python2.7/_strptime.py", line 325, in _strptime
    (data_string, format))
ValueError: time data '2003_02_05' does not match format '%Y-%m-%d'
