Initially display errors to stderr for console

[timkelty]

Description

If someone has a PHP error in a config file, it can be hard to diagnose when running a console command, as it will just return something like exit status 255, instead of something more helpful like:

PHP Parse error:  syntax error, unexpected token "->" in /var/www/html/config/general.php on line 16

Parse error: syntax error, unexpected token "->" in /var/www/html/config/general.php on line 16

Failed to run craft : exit status 255

This forces errors to display to stderr for console apps early to avoid this. Once config is loaded, it will end up resetting this anyway (based on devMode).
