Write tests for all commands

I just fixed bugs in the hypnotoad and plackup commands, which probably could have been caught by good unit tests.

While I am doing this I am also writing examples in both the .pod and examples/etc directory.

Oops didn't mean to close.

Left TODO:

• configure
• lighttpd
• plackup
• start
• status
• stop
