Extended functionality

Hi,

I just started learning Ruby and Sinatra. Because I'm the developer of JustNotes for the Mac (which syncs with Simplenote) I needed some easy ways to test my code. So I took your project to learn Ruby in more depth. I've made some changes and extended the functionality. My Ruby knowledge is only 3 days old, so I'm always willing to learn from other - any suggestions would be great ;)

Take a look at my changes and pull it if you want to!
