Subject: [PATCH] exit process with 0 code explicitly in case of successful
 command execution

Functions scheduled via setTimeout will prevent nodejs app from exiting.
In case truffle.js config contains code which calls setTimeout
(e.g. web3-provider-engine starts block tracker) truffle CLI
will 'hang' after successful execution of a command.
