Extend verbosity to the scripts and apps that pungi uses

[Joel Andres Granados]

hi list:

The idea is to allow, via a command line argument, the redirection of 
the output of the applications and scripts that pungi calls to the 
stdout of pungi.  In this way the user sees all that is happening.  
including the things that output of the stuff that pungi calls.  I 
havent tested this extensively and I'm just wondering what you guys 
think of the idea.
diffs attached.

Cheers.
