* 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#57Fixes#71
* Hide UI elements when sharing isn't allowed
* Implement a more robust Config
This moves the configuration variables from the `.env` file to a new `bewcloud.config.ts` file. Note that DB connection and secrets are still in the `.env` file.
This will allow for more reliable and easier personalized configurations, and was a requirement to start working on adding SSO (#13).
For now, `.env`-based config will still be allowed and respected (overriden by `bewcloud.config.ts`), but in the future I'll probably remove it (some major upgrade).
* Update deploy script to also copy the new config file
