SVS (and other Tails workstations?) should show hidden files by default

Description

Currently, decompressing a file may decompress hidden files in addition to regular ones. In case if a hidden file ends up in persistent volumes or ends up in the Transfer Device, Nautilus(?) should display hidden files in those places by default so that when journalists wipe selected files, they'll be able to select hidden files in addition to non-hidden ones.

As a journalist, I'd like to make sure I didn't miss any hidden files when selecting and wiping persistent volumes or Transfer Devices.
