Fix: illustration.js

removed duplicate entry for 'Party' and 'Celebration'
removed ambiguous terms 'Game' and 'Play' from matching with illustration of gaming controller [ game could also refer to any sports match, play could also be in a title for a theater play ]
added string 'Bike' to match with bicycle illustration
