Register IF statement - Take 2

[AmyStephen]

OK, here's another try =)

I split up the IF statement into single IF statements, and thanks to Davey Shafik, this time I created a little edit function so that I could return on the first error found, thus (really) not changing the logic like I claimed last time.

Thanks!

Thanks a lot Amy, can you please re-commit this into the develop branch ? I cannot (= dont want ;) ) merge directly into master. Big Thanks, you just fixed the internet a little bit tonight, some people got heart attacks because of that if/else stack.

why leave the else conditions would not be better to just leave the if's as a negative condition?

This has been a discussion before: "negative-first decisions are bad" is the conclusion afaik. But correct me if i'm wrong. @AmyStephen , what do you say ?
