Give proper name to folder zip

[fred1701d]

When downloading a folder as zip, the file is named Gallery.zip

Could we instead have a the zip file named after the folder name?

I have the code working locally. But I don't see option to create branches. I don't think I have permission to create branches and PR.

Here are the changes I'm proposing
I tested on :
-root folder
-test folder "its a along directory name. with special caracters(_.-.,-.,) 1234 56789 űáéú őóüö"
-subfolder

GalleryMWs.ts.zip

@fred1701d on github, the usual way to PR changes is to fork the project, push your changes on your fork, and then PR these changes to the upstream project. This is quite easy to do using the Github UI helpers.
