Prepare as a standalone component

Per the conversation on zendframework/zend-mvc#46, this is a proof-of-concept to detail how a component can be updated to work with a component installer:

• Adds the various service factories currently in zend-mvc for routers and route plugins.
• Adds a ConfigProvider, for use with expressive-config-manager, defining default dependencies.
• Adds a Module class, for use with zend-mvc applications, pulling configuration from the ConfigProvider, and altering the structure to suit zend-mvc.
