Adding database LWRP to the cookbook - used to manage the creation and (eventually) deletion of CouchDB databases.

Adding curl install to recipes - needed for LWRP.

Added user and password attributes to the database LWRP in case admin party is disabled.

Updated load_current_resource method to include new user and password attributes.

Removed call to database LWRP from default recipe - inadvertantly committed.

Moved create database commands to distinct method, using this to populate a shellout request from which a JSON response is parsed.

Removed erroneous "code" keyword prefacing the db creation command strings.

Corrected invalid call to shell_out.

Tried alternative means of calling shellout.

Fixed incorrect call to include? method.

Log fatal error if unable to create DB.

Changed Chef::Log.fatal to Chef::Application.fatal! - ensuring the Chef run is aborted.

Updated the README to document the database LWRP.
