httpserver: More organized startup output (#2497)

* Move SiteOutput to a seperate function sorted by port.

* Rename vars and tidy up

* Move loopback note to output loop

* Fix Typo

* Remove unneeded var

* Readability Change

* Change to other port string.

* 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

* change name of log in comment

* Remove spaces

* Remove extra line output

* final tidy!

* Use caddy.LogDestination to setup log

* Ensure Log is still output if quiet.

* Correct case of functions and make function param bool

* Remove conditional check for LogDestination

* Revert output to simple blocks

* comment update
