Uploading to imgup from Photos

Woof. It involved some AppleScripting, shell scripting, and some ugliness due to RayCast not wanting to inherit my login shell environment (circumventing rbenv to run imgup), but I finally got it:

• Pick an image in photos
• Fire off the action in RayCast
• Select a snippet format of `org` or `markdown`
• Provide an alt tag
• Get a copy/pasteable snippet back from imgup I can drop into the blog

I have a matching one for a selected file in the Finder.

Now I just need to go take pictures.
