Apply styles to Special:Upload to increase Accessibility and Interface Consisitence

The Problem

The current Special:Upload page is using a very native HTML form.

There is some accessibility problem with that, especially here in Citizen, where the input[type=button share the same color with the background plus the outline (border) is not quite apparent, it is not quite distinguishable. I often struggle to identify that "Upload" as a button.

The Solution

Apply styles from somewhere (like Codex?).

Also, the "Select a file" button always looks like a disabled one to me.
