Update plugin versions to those currently released.
Remove the GPG plugin, which the docs suggest should be installed locally. Made 'publish-local' prompt for a password, which fails when integrating with CI.
Updte version to 0.0.7-SNAPSHOT, build against Lift 2.5-SNAPSHOT and Scala 2.9.2.
Revert to 0.0.6-SNAPSHOT, shouldn't have incremented to begin with since it's just a snapshot.
