feat: Workspace view closing by pressing current workspace or empty space

[Adam-Cosner]

This implements #49 by closing the workspace view when the current workspace is clicked or the empty space outside of the window views is clicked

When updating a pull request you want to do a rebase rather than a merge. The merge also seems to have broken compiling, leaving a few includes of modules/types that don't exist.

But changing that, this seems to be working pretty well. I was uncertain if a mouse_area like this would intercept some mouse events that we want to go to child widgets, but I guess Iced handles this well.

Just fixed
