Title: Show only error output on cli crawling

Cron sends out emails everytime an output is generated. The ThinkUp Crawler generates lots of output. That's pretty annoying.
I redirected the stdout to /dev/null, but that still showed PHP notices. That's still pretty annoying, but luckily, you can set the error reporting level on the command line. I set it to E_ERROR and E_WARNING, which evaluates to 3. That should do it.
