Subject: [PATCH 2/2] Fix invalid cast

Since introduction of IgnoreJudgement and its usage in JuiceStream
and BananaShower the hard cast in CatcherArea that was used to check
if the drawable hit object should cause the fruits on the plate explode
at the end of combo caused a hard crash instead, since IgnoreJudgement
was no longer deriving from CatchJudgement.

Replace the hard cast with a soft pattern-matched cast.
