Feature: Added decrypting of logindata for our current ORacleDB database and our old AzureDB database
Add: CryptoUtils.java (for decrypting loginfiles)
Add: CryptoException.java (to catch multiple Exceptions from CryptoUtils.java Class)
Update: OracleDB.java, DBalt.java(added lines for decrypting and a method to get the decrypted logindata stored into variables)
Add: AzureDB_logindetails, document.encrypted and OracleDB_logindetails as a alternative to document.encrypted (These files contain the decrypted logindata for our database)
