Add IMG_BLOOM1.jp2 to standard asset set, which is used in stars.

This makes stars appear more realistically rather than as massive chunks due to the missing IMG_BLOOM1 asset from the viewer.
Thanks to YoshikoFazuku for supplying the star asset which I then uploaded via a viewer and extracted as JPEG2000.
Thanks also to Ai Austin for helping this process along.
See http://opensimulator.org/mantis/view.php?id=6691 for more details.
