Marcomix realsight tweaks+widescreen fix for EiB file

NOTE THAT THIS PATCH IS INTENDED TO BE USED WITH THE REALSIGHT MUTATOR BY RENDROC AND THE MRW REALSIGHT VERSION DEFINITIVE EDITION 2.0 (THE FILE HAS BEEN UPDATED IN AUGUST 2015). the front sights has been tweaked to enhance the realism (now the sizes are more believable). Each weapon model has been tweaked to guarantee a full screen experience even in 16:9 resolutions. Also, the bug during the ADS view has been solved. To install: Put the files inside the archive into the "animation" folder of BiA EiB. Enjoy!
