New version is already available. Finally added the connections frame. You can save/edit atributes (alias, login, password, server, port, comments) of your most used connections.

Added features:

You can save/edit attributes of your most used connections. Information is stored in the xml file 'conn.xml' in the configs folder. When you click on the Connect/New/Edit button, the login frame will be raised. The Clear button in the login dialog will clear all the input fields, port and server will default to localhost:3306. The passwords are stored encrypted using symmetric encryption "DES" in the file 'configs/psswds.properties'. The key for en/decryption is stored in file 'configs/key'. The 'passwds.properties' file uses combination of server, login and alias to pairs it with a certain password.
