Fix issue with Shebang for web server

[Casey McLaughlin]

The PHAR needs a sehbang line to work as intended in CLI mode, but the shebang breaks web output. So, the best option I believe is to never use the PHAR itself to serve pages.

Instead, include a CLI option to build an index.php that handles requests.. In the init script, we can also add an option to include the index.php.
