Change default profile-dir

Change default profile-dir to be under
For Windows: %localappdata%\Telerik\BlackDragon
For Mac OSX: ~/.local/share/Telerik/BlackDragon

We have decided to use ~/.local/share/Telerik/BlackDragon for our cache on Mac. The reason is an environment variable, that is used in our Simulator code and it is resolved as ~/.local/share on Mac. It could be changed to  "~/Library/Application Support" in the future.
