Add the ability to store connection passwords in a password-protected keystore.
At the moment, connection passwords are stored alongside other connection parameters (like host or port) in the "connections.xml" file.
This file is not encrypted and passwords are then stored in plain text and visible to anyone.
While it's very handy because the passwords are always remembered and the users doesn't have to type them anymore, it would be useful to have a way to store those passwords in a password-protected keystore.
This keystore would need to be unlock when accessing a connection password for the first time.
