Actually it would make sense to write a general Tool for this,
instead of handling this inside the engine.
(Idea for the Tool-contest)

Like a "Start App" Tool, that contains:

-A starter-splash
-some options like screen-res to select
-A "info" Button
-A "START" Button (starting the exe, in this case acknex)
-A "Check for Updates"
(wich contacts the server, checking for a new version number,
and then downloading automatically the updated assets)
