UI feature request: <<download all>> button for outputs

[hmedina]

If I have 20 snapshots in the UI, I have to hit export 20 times. It would be nice if there were an export all button right of the current export one. The drop-down format selection would also affect the behavior of export all, so the user could select to export everything as .ka, .json, or .png.

DONE ! Well, export formats are hardwired :-(. This is not trivial to give a choice to the user... Hum...
