GUI: Disable Current View Selection Button in Save/Load Chooser.

Switching between List and Grid views causes a nasty redraw flicker.
This also occurs if you press the button for the current view type.

This patch does not fix the underlying refresh issue, but it does
disable the button for the current view type as pressing this is not
useful in any case.

This is a partial fix for bug Trac #10441.
