Updated note in readme about firmware upgrade
minor hsl fixes in web example

this tweak fixes a couple issues I was having:
- Buffer.writeUInt16LE() was throwing out-of-bounds error when it encounters fractional  hsl values. 
- I think maybe the intent was to cap saturation at 80%, but instead it was being scaled to 120% (causing overflow).

and IP addresses are now accessed via the gateway.ip property.
Debug mode should default to false now that this works with the lastest lifx firmware
actually, just remove this line altogether
