Server code with some buttons.
//zoomkat 8-04-12
//simple button GET server code to control arduino pins
//for use with IDE 1.0 or later
//open serial monitor to see what the arduino receives
//use ' instead of " in the html
//address will look like http://192.168.1.102:84 when submited
//for use with W5100 based ethernet shields
///note that the below bug fix may be required
