Bump version to 0.0.10

Changes
 - Minor change for unicorn_rails - no longer passing through the -P
   argument to set the PIDFILE as this is not supported by
   unicorn_rails. User much manually match up PIDFILE argument to
   unicornherder and the pidfile config option in configuration file
   used by unicorn_rails
