Rolo 010 Released With A New `query_command' Utility

Added a new utility for mutt's `query_command' called `mutt_vc_query'. This utility will allow a mutt user to query the email addresses in `contacts.vcf' with the `Q' command in mutt. See the README file for how to implement. Rolo is a text-based contact management program with an NCurses front-end and a vCard file as its storage structure.
