Allow to bind certain apps to open on a defined workspace

I think it would actually encourage people to use workspaces more by letting them to configure what app opens on what workspace by default so that when they open an app, it opens automatically on a specific workspace.

Say e.g:
First workspace: browser
Second workspace: code editor, terminal
Thrid workspace: music player

It could also probably be reported in https://github.com/elementary/switchboard-plug-applications instead of here.
