Proposed fix for "green blob" problem (Issue 3327). 

At first I was looking for ways to make the box go away, but then I figured why not have some fun with it instead? :) This fix uses the box to display a cute caption for each prospective class. As a result, it depends on having a $classCaption value in the i18n files. I've submitted English ones to the habitrpg-shared repo here:
