Recoded MySecretKey.java to UTF-8

Perhaps this is the best way to fix the encoding problem. 
I only had problems with this file. 
Running "recode" 

recode ISO-8859-15..UTF8 cloudgene/cloudgene.cluster/src/cloudgene/util/MySecretKey.java

Fixed this.
Perhaps every source file should be in UTF-8 for better multi OS support? 

cheers
