retropiemenu/gamelist.xml grows every time retropie-joystick-selection is updated

Hi!

Just wanted to give you a heads up, I noticed that when the script is updated, it appends the following lines to gamelist.xml in the retropiemenu directory:

<game>
	<path>./joystick_selection.sh</path>
	<name>Joystick Selection</name>
	<desc>Select which joystick to use for RetroArch players 1-4 (global or system specific).</desc>
	<image>./icons/joystick_selection.png</image>
</game>

Because I have updated my packages several times, I have 5 entries of the above code in the gamelist.xml file, one after the other, when there should be a single entry.

I was able to replicate after noticing this by purposefully updating a 6th time - and indeed another entry was put in.

It doesn't seem to cause an issue fortunately. However for tidiness, is this easily fixable?

Let me know if you need any more information. This script is great, it really has helped with my Picade and second controller. I always want the 'on board' controls to be Player 1, and by using this script it now works exactly as required (I use the 'by-name' method).

Before installing this script, it was not possible, so thanks for creating it.

Thanks!
