Modify Startup Output (#2469)

* Move SiteOutput to a seperate function.

* Simplify as all sites in Server use the same port

* Ensure -quiet supresses fmt.Println calls

* Prevent double output of siteinfo to log - improve log message

* Use caddy.LogDestination to setup log

* Ensure Log is still output if quiet.
