Pull Request for Issue 803: Remove Commented out Code 

Significant changes to commented out sections of code over many files. I've removed a lot of these sections, but I've also replaced a number of sections with /**/ style comments if I thought there was any chance people would want to keep it. @dretrex @epengr @helfrij , would you mind quickly taking a look and make sure I didn't nuke anything you really wanted (also feel free to nuke more if you want to).
