Hangmanduino Update

I tried compiling Hangmanduino (see original post here) again using v 0021 of the Arduino IDE and found out quickly that things had changed. So I began troubleshooting and found that the WString library I was using was obsolete in the new IDE. Long story short, I was able to make a few adjustments to the code and got it up and running. Get the new code here (no need to download any additional libraries).
