[Plugin: Pick Giveaway Winner] Add a rule to search for a special phrase?

Hey there,

I´ve installed the plugin on WP 3.3.1 and it works like a charm.
It´s the perfect wordpress plugin to pick random winners.

I don´t exactly need it right now but I thought it might improve
the plugin if there was an option to only pick comments that contain
a specific phrase. In example: “I want to win product whatever”

As many giveaways are build upon that rule it might be good to add it.

Cheers
