Construction of modules

Finally started putting the temperature, humidity and pressure sensors together. Added in a DHT22, BMP085 and ENC28J60 ethernet module. Downloaded the following libraries: ENC28J60 Ethernet library DHT22 Humidity sensor library BMP085 Pressure sensor library Had to hunt around a bit for libraries that were compatible with the new Arduino Software
