FLUID-5335: Uploader HTML5 Refactoring

Refactored uploader so that it will work in HTML5. This involved updating the HTML files to be valid, part of which was removing the summary attribute from the tables. This resulted in a larger refactoring of the uploader to move that information to the status area. 

Note: this pull only covers the uploader related changes.
