Photosphere available as Universal

If anyone has one of the new Intel-based iMac's already, please try out the Universal version of Photosphere I've posted to <>. It's a bit crippled, because it doesn't read or write TIFF or OpenEXR files right now, but I'd like to know if it's at least working on the Intel. In particular, I'm curious whether you can read your previous catalog file and write it out again successfully.

WARNING: Please make a backup copy of your catalog (*.adb) file before trying this out!!

I am not sure I have byte-swapping implemented correctly. I'm also curious if the Intel-based Mac's run the old version of Photosphere or not.
