A loading button while exporting

While doing an export, sometimes the downloading process takes long time, the user needs to see that their request for downloading was taken into account and it's in the process. There needs a loading button.

@marek.ostaszewski it's not easily fixable (it's been always like that), the problem is that you click on the link that downloads the file, and it's browser responsibility to handle show it properly...

I could probably try to fetch it in the js and provide a content to the user after I fetch it, but it's a bit tricky
