Drive applet by default

[David Prieto <frandavid100 gmail com>]

I've noticed that some people coming from windows have trouble removing
USB devices and the like, because they don't quite know what to do to
"safely remove the device".

They come from windows and they're used to look into the system tray to
unmount removable. There's no way for them to know that they have to
right-click the desktop icon, then navigate the options they're given
until they find the "secret" (as in "doesn't show on any other desktop
icon") eject option.

The drive applet offers a handy solution for those people, and remains
unobstrusive because you don't even see it unless there's a device in,
but you can access it anytime without having to show the desktop. So I
think it would be a good thing to have it included on the panel by
default. Another good solution would be to get a notification balloon
each time a USB device is inserted, to inform the user about the needed
procedure, and a second one to inform them that the device can be
removed, just like windows does.
