Public File Sharing (#72)

* Public File Sharing

This implements public file sharing (read-only) with and without passwords (#57).

It also fixes a problem with filenames including special characters like `#` not working properly (#71).

You can share a directory or a single file, by using the new share icon on the right of the directories/files, and click on it to manage an existing file share (setting a new password, or deleting the file share).

There is some other minor cleanup and other copy updates in the README.

Closes #57
Fixes #71

* Hide UI elements when sharing isn't allowed
