FileNotFoundException on Linux

[TheCherry]

On Linux I get a ton of java.io.FileNotFoundException.
The Installer tries to download the files to: /tmpskyclient-universal-cache/
Seems that a slash is missing, it should for sure be: /tmp/skyclient-universal-cache/

FileSystems.getDefault().getSeparator() works better.

Here is a fix for this:
sudo mkdir /tmpskyclient-universal-cache
There you create the folder in the root dir.
sudo chown username:group -R /tmpskyclient-universal-cache
There you set the rights for the folder that you can access it.
