starting work on an API abstraction for daemon script generation.
fixed allservices only returning self-referential services for global packages
making daemon script generation async.
pulling OS-specific logic into platform-apis plugin directory.
had global flag set twice.
should be Centos not Darwin.
refactored start|stop|restart so that it's handled by API.
made isPlatform an instance method.
Merge pull request #66 from npm/platform-api
