Ardamon Code

Spent most of the time working on the arduino board, as I got my Ethernet Shield. Temperature upload and requested temperature are functionnal. Some parts of the code are broken (ie : graph and widget can only work on sensor_type), but most of the platform is up and running here. Value schedule is functionnal (ie : what temperature should I get at what time), but there's no form for managing them. Getting hands dirty in the database is required for now.
