Improved memory usage in Espruino

I'll start doing those tests tonight or tomorrow. Seeing that 3250 jsvars is such a beautiful sight; so far my code uses around 1800 just sitting there (with a few hundred used when it's doing something)

The json the page is serving is valid... I'll need to throw in some console.log() to see if it's somehow not getting the whole thing?

{"relaystate":[ {"state":0,"rdtiev":0}, {"state":1,"rdtiev":0}, {"state":0,"rdtiev":0}, {"state":0,"rdtiev":0}, {"state":0,"rdtiev":0}, {"state":0,"rdtiev":0}, {"state":0,"rdtiev":0}, {"state":0,"rdtiev":0} ],"fargostatus":{ "temperature":38.5, "volts":11.02 }}
