previewed FITS on 'droid

Finally found a solution for previewing FITS image files on the Android thanks to some code by Elwood Downey over at the Clear Sky Institute web site.

I tried two Android apps, FIV and ioda, without any luck. Downey's HTML and single, small (50 KB) Javascript library was easy to implement.

Hacked it slightly on John Charles and transferred it to Ananke. Saved it to the external microSD memory card. Sadly, Chrome doesn't like that. But it works fine with the ASUS browser (v2.1).
