Remove the CGI rocks

Why: In the Blu-Ray version, for God-knows-what reason, Lucas decided to have R2-D2 hiding behind new, CGI rocks. Besides the fact that this was a completely useless addition to the movie, it also creates a continuity error because those rocks are no longer there in the next scene! Moreover, they're packed so tight that it's anyone's guess how R2 got in there in the first place... My suggestion: get rid of them!
