This new version is still in a state of partial completeness. You may need to do
some manual fixing to get it working, due to a change I made in the classes
offered by this module. Try 'drush cc registry' if 'drush cc all' fails.

Please note that ALL of the hooks exposed by Date iCal have changed. They do
essentially the same things they used to do, but they're named differently.

The big change is that the Feeds plugin has been completely re-written to
conform to the Feeds APIs. It's now much more resilient and powerful. Feeds
Tamper will now work, and is in fact the prescribed way to alter data, since I
removed several alter hooks.
