Applied patch and committed substance.jar to trunk

Please review and apply to internal and community trunk

moved the relog WIP patch to

I have tested your WIP patch. It works fine. And i really think we need separate ticket for this and maybe also rework other parts with Spark restarting (like when changing the language). I do prefer it auto logins after such restart and not just show login screen. Though i would prefer to hide login screen (now it pops for a seconds and then auto logins), probably the same how it doesn on a normal startup when start in systray is selected. Also this confirmation dialog should be translatable via i18n files.

I will probably test it some time later. But maybe we need a separate ticket for this? So if the have issue say in skins, we won't have to reopen it for both patches, or if the won't use Substance anyway.
