Non-verbose, floating point, list commands, force uppercase

Hi, Hope I'm doing this right. I'm new to this.

I've been using cmdArduino in many projects (very useful!) and I've made some changes to my copy to support some things I needed. They might be of general use, so I'd like to submit them for consideration.

Again, hope I'm doing this right, please let me know if I'm not.
