[9] Review request : 8038919, Requesting focus to a modeless dialog doesn't work on Safari

[mikhail cherkasov]

Hello all,

please review the fix
http://cr.openjdk.java.net/~mcherkas/8038919/webrev.01/
bug: https://bugs.openjdk.java.net/browse/JDK-8038919

The problem appears if we trying to call toFront when embedded window is 
active in browser, this
call is ignored, because for macosx the browser process is active and it 
ignores
 [nsWindow orderFront:nsWindow] call to java process windows.
To fix this issue I use  [NSApp activateIgnoringOtherApps:YES]; before  
[nsWindow orderFront:nsWindow]
if an embedded frame is active window.

Thanks,
Mikhail.
