cantaloupe detector per shuv

Each time "cantaloupe" (case insensitive) is found on any page you have open at the time of add-on installation, it will immediately play Invincible by Deaf Kev in low quality for the full duration of 4 minutes.
And it will also play after installation when text changes on a page and that text is "cantaloupe".
Each cantaloupe spawns a new instance of the song, so have fun and turn down your volume.
