The current bin/shoes.bat doesn't work on Windows. So, I did the following.

- bring back swt-shooose.bat
- delete the current shoes.bat
- rename the file name from swt-shooose.bat to shoes.bat

Now `C:\tmp\shoes4>bin\shoes samples\simple-sound.rb` works on Windows.
Add three adjusted samples, i.e. expert-irb-adjusted.rb, expert-pong-adjusted.rb and expert-tankspank-adjusted.rb.
good-reminder does not work and crashes for me - refer to #188
