Minefield defused

The openinfocard id selector now works with Firefox3.

The bug in Firefox3 is not fixed but circumvented. Firefox3 treats arrays of java objects differently than before.

In a javascript script the call "java_method([aElement])" formerly worked but now it fails. It has to be replaced with
var urlArray = java.lang.reflect.Array.newInstance(java.net.URL, 1);
urlArray[0] = aElement; // aElement beeing a java.net.URL
java_method(urlArray);

Please download the latest version in the openinfocard download area.
