artisan serve exit code

[BMacster]

Description:

Artisan seems to ignore exit codes. A forced error always returns zero.
Attempting to write an actual sysv init wrapper.

Steps To Reproduce:

Do something zany and nutty like try to bind to port 98080 or pass invalid switches, as far as php is concerned it exits clean even though there was an issue.
php artisan serve --host=0.0.0.0 --port=98080 ; echo $?
Laravel development server started: <http://0.0.0.0:98080>
Invalid address: 0.0.0.0:98080
0
