- Added new config option `deleted_sets` which can be used to make all resources within a specific set `oai deleted` within the context of a specific feed. In many cases this is preferable compared to `disallowed_sets` since resources will just dissapear when they are not allowed without leaving a proper deleted resource behind.
- Disable ranged HTTP requests in Apache mod_python backend. This was giving problems with acrobat plugin and its "Fast Web View" feature.
- Show records sorted on descending datestamp, instead of ascending record id, in sqlite backend.
