RouteConverter and Mac OS X

[hvdwolf]

If you like to set them, put them into the class Constants. There is a section

if(Platform.isMac()) {
...
}

where I've already set some properties.

I played around with them and tried some options and combinations but did not get a better result. Actually I could not detect any change at all in performance.
The "System.setProperty("apple.laf.useScreenMenuBar", "false");" should be set to false otherwise there is now menu visible at all.
