Rednet testing implemented! Modem stuff...

+Added debug mode (After the program accidentally somehow force updated,
making me loose all my work)
+Added some rednet stuff (Currently only changes sides and turns the
modem on/off)
+MAJOR BUG FIX! Turns out, I had a function called "shell" and when you
would exit the program via termination, ALL programs using the shell api
would break, causing the computer to break. Completely fixed now,
thoroughly tested.
