Update Automator stuff (for Mavericks/10.9?)
Add check to handle "Cancel" button selection
Calculate effective focal length based on sensor size

Had to add hard coded list of FX vs DX cameras,
and requires looping over each file via bash, vs.
sending entire file list directly to exiftool.
Update how result and notifications are displayed

Removed usage of Growl, use notification center
instead.
Streamline how the lenses are defined in the drop down

Match on entire lens name now, instead of leading
number.  Avoids having to reorder when adding a new
lens.
Add Nikon D750 to full-frame camera list
Remove trailing whitespace
Get rid of weird end-of-line characater issue?
Update case blocks to use variables

This prevents entering the same value multiple times,
in theory should make it easier to update later.

Also converted all spaces to true tabs.
Convert spaces to true tabs in rest of bash script
Update readme with new info after recent changes
Fix indentation on some closing double quotes
Add lenses: Nikkor-O 35mm f/2 and Micro-Nikkor 55mm f/3.5 Auto
