gauge.js: fix when inadvertently sending string instead of numeric data

[GoogleCodeExporter]

If passing a string for the value to set the control to, an error is triggered 
in gauge.js:

     ret = value.toFixed( decimals );
     while ( ( decimals > 0 ) && ret.match( /^(-)?\d+\.(\d+)?0$/ ) ) {
       decimals -= 1;
       ret = value.toFixed( decimals );
     }

Changed to:

   ret = (parseFloat(value)).toFixed( decimals );
   while ( ( decimals > 0 ) && ret.match( /^(-)?\d+\.(\d+)?0$/ ) ) {
       decimals -= 1;
       ret = (parseFloat(value)).toFixed( decimals );
    }

Just forcing the conversion here.
