Changed script name from 'munki_installer.sh' to 'Wrench' as it seemed appropriate and also it makes it easier to use in CLI. Also changed 'munkitools.dmg' to 'Munki.dmg' since thats the original name anways and it looks cleaner. There are a lot of updates wiht the script that includes a logging feature, but its very fragmented and needs updating, but does work. Squashed a pesky bug that caused issues with detecting ManagedInstalls.plist and completed the installer of the Munki.dmg package.
