Improved the download page like it is suggested here

What's the purpose of this class? Could this be solved using padding or margin instead?

[msemple1111]

It should have been solved that way. I have corrected it to use margin instead now.

Aside from the code style and code problems, the UI is a bit confusing. Re-using the upload dialog is confusing as previously that sort of UI is a drop zone for files and now it is a download button so it seems weird as a pure button. But aside from that small confusion the UI itself looks bad because the large box is not centered vertically and its hard for the eye to find a space. It would be better with a smaller download button and if you really want a box putting a border around the whole thing.

I updated the UI according to your suggestions @andre-d. I'm not particularly good at UI design so welcome any suggestions!
I have fixed the code problems you mentioned @k3d3. I think that is it but if you find a few more, i'll gladly fix them too.
