Venus Migration

## Migration from Planet 2.0

The intent is that existing Planet 2.0 users should be able to reuse their existing `config.ini` and `.tmpl` files, but the reality is that users will need to be aware of the following:

- You will need to start over with a new cache directory as the format of the cache has changed dramatically.
- Existing `.tmpl` and `.ini` files should work, though some configuration options (e.g., `days_per_page`) have not yet been implemented
- No testing has been done on Python 2.1, and it is presumed not to work.
- To take advantage of all features, you should install the optional XML and RDF libraries described on the Installation page.

Common changes to config.ini include:

- Filename changes:
