2.2.0

Upgraded dependencies: express, optimist
Declared compatibility with node 0.4 and 0.6
Fixed: showError middleware no longer writes a body for error responses to HEAD requests.
Changed: Server.initialize() and Server.conclude() are now passed all arguments for the Server() constructor instead of just the plugin.
Changed: Default model routes now allow Error() objects passed back from Backbone.sync() to be sent to the client.
Changed: Default value for host command option is false, which disables host checking by default.
