Just remembered, this beast needs to get reviewed before we can bring in the new version of Vellum.

I added them while testing the Upload Download dialogue that uses flash buttons as in Mutimedia Uploader in the App manager. But I didn't remove them after deciding not to go with them. These can be removed. 
Sorry, I should have checked what I was committing. I am using interactive git staging now.
