Parameters for http-binding

[GoogleCodeExporter]

Sending the actual value of SetPoint (and maybe also for the Slider) as a 
parameter to the http-binding.

Example: Number Temp_OG_Bath_soll   "Badezimmer [%.1f °C]"         <temperature>   (og) 
{ http=">[ONCHANGE:GET:http://192.168.0.22\set.htm?temp1=VALUE]"}

Where "Value" is replaced with the actual value of the element.

The HttpOutBinding now utilizes the String.format() method. The current date is 
the first parameter and the current value (command or state) is passed in as 
second parameter. So an url can be formatted like this 
"http://host:port/resource?value=%2$s" when expected a string.

See java.util.Formatter for further details how to format String appropriately.

The complete binding String would look like (since the value is passed as 
second value):

{ http=">[GET:http://192.168.0.22\set.htm?temp1=%2$.1f] }
