Title: Moar PHP Exercises: Part 1

I changed up the `config.json` so that the exercises were in what I felt was a more realistic order (and matches exercism/xruby

Added:
* Raindrops
* Robot Name
* Roman Numerals
* Difference Of Squares

I'll try and get a few more of these done over the next few days, but I thought I'd drop in today's efforts :)
