version 1.2.2 (build 5)

jpeg rotations (not grayscale) now also apply to exif thumbs
(there seems to be some extraneous stuff in the ifd1 of the exif, seems safe to delete)
can reset orientation tag and auto-rotate by them
rotating resets orientation tag
better prefs window
left- and right-click now go next/back
dbl-click to end
scroll wheel to navigate, but it conflicts with scroll wheel to scroll zoomed images
+-= w/ cmd key held down can now zoom (= on numeric keypad only)
hand cursor shows up for dragging zoomed images
set bg color, transparency for slideshow
fixed: jpeg files with non-EXIF APP1 tags would cause problems with selection/info display
fixed: jpeg rotation during slideshow didn't update if "don't change modification date" was checked
fixed: rotating and trashing in thumbs window will now cause slideshow to update too
fixed crash when exiting slideshow with images waiting to be cached (also made currentIndex volatile)
changed supported file types from imageFileTypes to imageUnfilteredFileTypes
 (seems to make no difference, 106 types both ways)
'@' to auto-advance 1.5 secs (not official... try to have better interface in future)
made columns resizable
