moused - Ease usb mouse attach/detach

WARNING: Upgrading will overwrite your /etc/devd.conf.

Extend /etc/rc.d/moused. To attach e.g. ums0, you can now call:

    /etc/rc.d/moused start ums0

To detach:

    /etc/rc.d/moused stop ums0

If moused is called with an explicit device name, it is enabled by default
(moused_nondefault_enable="YES").

You can explicitly override any settings in rc.conf with directives like:

    moused_ums0_enable="YES"
    moused_ums0_type="..."

If you have one or more ums[0-9]+ mouses, you can now make use of them by
simply setting devd_enable="YES" in rc.conf.
