hardcoded path

swish.module contains hardcoded "files" path inside. This means it will not work for sites where default path setting "drupal_root/files" has been changed to a custom path (like "drupal_root/some_other_file_path").

Attached is a patch that is using a variable $index_dir which takes current "files" setting.

Hope the attached patch helps - please bare with me in case my assuption was wrong, as it's the first try to submit a patch.

Thank you,
Silviu
