- Added proper swap creation, also "ephemeral" disk support
- More robust instance state reporting to Cluster Controller
Web interface improvements:
- Added cloud/Walrus configuration, including clusters and VM types
- Revamped 'credentials' tab with new options to edit user information and hide/show "secret" strings

Cloud Controller:
- User, Cluster, and System keys are now stored in PKCS12 keystores and have moved to var/eucalyptus/keys
- Configuration is handled entirely through the Web interface
