Tune VPN-X security

There are some security parameters to tune and make VPN more secure.

Example:
javassl.keyStore=default/serverkeystore
javassl.keyStorePassword=ENC\:e7OtWalJVcg\=
javassl.needClientAuth=false
javassl.sslName=SSLv3
javassl.trustStore=default/clienttruststore
javassl.trustStorePassword=ENC\:e7OtWalJVcg\=

If you generated your own SSL certification or key, you should change those parameters.

Tips: javassl.keyStorePassword and javassl.trustStorePassword can be inputted plain-text word. VPN-X will encrypt the password automatically.
