Customizable variable "emacspeak-play-emacspeak-startup-icon" gets reset to t

[Parham Doustdar <parham90@xxxxxxxxxxx>]

hi,

When I customize `emacspeak-play-emacspeak-startup-icon` and set it to nil, it gets set to t outside of customize.

I looked around in the emacspeak source code, and it seems that the problem might be related to how the variable is defined.

In emacspeak.el, it is defined using `defcustom`. However, in `emacspeak-loaddefs.el` it is defined again, and autoloaded.

So in other words, to me it looks like the variable is defined twice.

Thanks!
