Title: Allow CSS classes for buttonHover and buttonFocus to specified in options to FileUploader

Currently, the `FileUploader` creates an `UploadButton`, but provides no way to specify the CSS classes to be used for the hover and focus on that button.
This patch adds them to the 'classes' object in the `FileUploader` options.
We need this because we use _FineUploader_ in a GWT project with obfuscated CSS files, so we need to be able to control all CSS class names.
