Two helper methods

These two helper methods are in some other open source libraries but we don't always include those. It bugged me enough that I added them here.

Latest "vallum ajaxupload.js" that is in vallum's old repository.

The version of this we had been using was not compatible with Firefox! Replacing with the latest version solved this and still works in Safari and IE. This version of vallum's uploader is old news and will no longer be updated by him. He has a new "pay for" version. We may have to revisit this in the future or look for alternatives down the road.
