Modify spec file to support a user-defined config.js rather than using exampleConfig.js.  Moved config.js and statsd-init to sources directory.
Modify spec to install config.js (SOURCE2) from SOURCES dir.  Also, use post hook to start the service after installing the rpm.
Update README to support new sources dir, use the example config.js.
Merge pull request #5 from brightcove/master
