ESP8266 net display

Using the previous lcdprint function here is a simple remote display. To display on it from your server you can use wget (or nc or whatever) eg.

a message
wget "http://xxx.xxx.xxx.xxx/?message=This%20is%20line%201&line=1&col=0" 
the time and date
wget "http://xxx.xxx.xxx.xxx/?message=`date +"%H:%M %a %d %b"`&line=2&col=0"
 

Here is the code based on the toggle_pin.lua webap (here)  Run node.compile() on this as well as the lcdprint or it runs out of heap.

   end
   local _GET = {}

     for k, v in string.gmatch(vars, "(%w+)=([%(%)%-:%w%s%%]+)&*") do
