Release 6.20.1: The package open-xchange-admin-plugin-usermove was renamed to open-xchange-admin-plugin-user-copy

[changerequest]

Not only the name of the package but also the name of the corresponding bundle has changed. Instead of com.openexchange.admin.usermove it's now called com.openexchange.admin.user.copy.

This also affects the commandline tool that is called usercopy instead of usermove now.
