Formatting & Server OS Agnostic

* Edited the ./sh/*.php files to have consistency, description, and notes.
* Edited the ./sh/*.php for proper file endings (note)
* Edited the ./sh/*.php to include the ability to use the server dashboard in (*)nix and MacOSX environments
* Edited ./sh/whereis.php - removed shell 'whereas' replaced with 'which' in order to make OS agnostic
* Edited ./sh/top.php - general code cleanup and formatting; couldn't find where this was used?  Is it?

Suggestion: drop un-used files and/or code blocks that are no longer needed.
