Subject: [PATCH] Add CLI options to display app and user data directories

For Windows, it was necessary to add a batch file "mdview-cli.cmd",
because Electron behaves weirdly on a Windows command line. The Electron
process detaches from the calling command line and outputs overwrite
other outputs, e.g. the CLI prompt itself.
