Indicate presence of undisplayed hidden files with empty message

[jeremypw]

Fixes #1278

BEFORE

AFTER

• Completely empty folder

• Only hidden files

[teamcons]

if we mention hidden files we may as well straight up display a button to show them, instead of "lol go find it yourself" ?

@danirabbit What is your opinion of adding a "Show Hidden" button in this context?

[jeremypw]

OK, so should it change the global setting or just reveal the hidden files for the folder in question?

[teamcons]

A one-time "display this folder" that lasts only till you change folder could be nice

[jeremypw]

That would be possible. My only concern is that there would be no obvious way to revert the step without reloading or navigating away from the folder (the appmenu and context menu would still show hidden files are not shown). Its not a big deal though I guess.

@teamcons Latest commit implements a basic implementation of you idea. Instead of having two labels, there are now only one showing at any time - corresponding to the two relevant situations. I have also avoided the words "Empty Folder" as it is rather ambiguous.

[teamcons]

"This folder contains only hidden files" ?
"hidden files are present" sound slightly ominous
That is a nitpick tho. Pretty cool and thank you for adding this. It feels more "aware"

[jeremypw]

I wonder whether the button should show below the text? Any styling required?
