roundcube 0.3rc1 change password plugin

[BeNe]

I started also to get the new Roundcube with the plugin API running.
But the old files doesn´t work anymore because of the Plugin API.
The old PasswordChanger isn´t support anymore - so we need to rewrite the Plugin or change the current PW Changer that comes with RoundCube.

A "ispCP Password Changer" as Plugin would be the best (Confixx and ISPConfig has also one)
With such a Plugin for Roundcube is no more Patch needed and we could easy add the PW-Changer.

Managesieve is also a default Plugin, in combination with DoveCot is the Mailsystem very rich in features.
