grunt-contrib-concat should be able to concatenate binary files!

Well, if I'm going to complain about it, I'd better put my money where my mouth is, huh? Good thing that's how I roll. :)

If you're looking to concatenate binary files using grunt-contrib-concat, go check out/support my pull request: https://github.com/gruntjs/grunt-contrib-concat/pull/86/files

Instead of assuming we're using strings, it now uses buffers and direct file reading/writing. I needed this while working on the distribution system for my upcoming game engine. You can check it out at avocado-baseline if you're interested! It's still early, but with a little skill you can already get it working and have pretty pictures dancing around on your liquid crystals. ;)

Peace~
