[Sandbox] selectManyPicklist button text

[Bharath Belagodu]

The selectManyPick component in the sandbox provides a '<' and '>'
button. I was trying to figure out if I can change the text of the
buttons to 'Add' and 'Remove' instead of '>' and '<', but after looking
at the code in the renderer of the component I figured that the text of
the buttons are hardcoded, 

encodeSwapButton(facesContext, uiComponent,
        javascriptRemoveFromSelected, "<");


>From my current understanding there isn't an option for me to change the
text of the buttons?
