move the favicon to the top level (outside /img) to fix Firefox bookmarks
The favicon for our view is stored in the /img folder within the customization package.
For Firefox to display it correctly when I have the URL in my bookmark bar, the favicon needs to be outside the /img folder.
"the saved bookmark favicon image was located in other than the website server file path root directory which was the original W3C standard for favicon placement for web browsers to loom for it"
As long as the favicons are stored within /img, they display ok in the tabs of Firefox, but get lost when I drag the URL the bookmarks toolbar.
