Convert shader reading code from C-style to C++ iostreams about distortionizer

Thanks for pointing this out. Step 1: Copy-paste from an existing project. Step 2: Hand off code that is halfway written before I've had the chance to check and clean up.

The same excuse won't work for VRPN, of course. Looking forward to using standard libraries there as well. You can assign this to me if you want, but I won't get to it until after the latency is licked.

LOL, no worries, I totally get the "hand off partially finished tool" thing. Just wanted to put this into the issue tracker while I was doing the same with other stuff.
