Adding New Relic installation capability
Adding support for New Relic
Fixed some tab / space issues and if statement in extract_php_info
Moved New Relic config to occur after New Relic extension is installed.  If it installs, it should also configure itself.
If php.ini file contains the word 'newrelic', it will disable automatic configuration of newrelic
Changed NR_INSTALL_KEY to come from the config
Changed the logging to be a bit less verbose
Updated README
