[Mailman-Developers] [CLI Project] Code refactored as per feedback

[Rajeev S]

Hi,

As per the feedback from Steve, I have made changes to the code in 
following areas

- The get_listing method has been moved to the lib/utils and has been 
rebuilt in a class
    *independent* way, and it works as good as before.
- The connection checking has been moved to the connect function, 
without the need
   of making a database call, by checking the Mailman version using 
client.system
- The addition of CLI colors has been made more generalized by making it 
a module level
   variable, with colors stored in a separate file.
- Removed class attributes from Filter class, and changed them to arguments
- All files now have a header acknowledging the support of Google, along 
with the names and contacts
   of mentors.

I will be improving the error handling, as mentioned in the comments, 
with the next revision.
