Title: Add - (NSArray *)targets support to GPUImageFilterGroup

Targets are added to the terminal filter in GPUImageFilterGroup, so calling "targets" on this class should return the terminal filter's targets array. Currently GPUImageFilterGroup's superclass (GPUImageOutput) responds to this method, which returns an empty array.
