[Feature Request] Support for folder/multiple files selection in upload dialog

[dierochade]

The file upload dialog does not allow to select multiple elements nor folders as a whole.

Therefore

• it cannot be used for rather beginner tasks like adding a custom component
• user is required to use scp, ftp, ssh or network shares?

Would be very good to have a solution in the application itself

This would require a major rewrite of the embedded webserver. But it can be done by anyone who is willing to contribute. 👍
