pp 6.0: small typo showgallery

[Astaran]

There's a small typo in showgallery which causes invalid css:

Search for:

$quickjump = "<select name=\"cat\" style=\"font-size: 9pt; background: FFFFFF;\">$catoptions</select>";

Add a "#" before the color:
$quickjump = "<select name=\"cat\" style=\"font-size: 9pt; background: #FFFFFF;\">$catoptions</select>";
