improve encapsulation of workspace window object * workspace-view.h, workspace-view.cc (workspace_view::handle_visibility_changed): Delete. (workspace_view::workspace_view): Set status tip. Don't connect workspace_view::visibilityChanged signal to workspace_view::handle_visibility_changed. (workspace_view::connect_visibility_changed, workspace_view::focus, workspace_view::handle_visibility): New functions. * main-window.h, main-window.cc (main_window::workspace_window): Rename from _workspace_view. Change all uses. (main_window::main_window): Initialize it. (main_window::focus_workspace, main_window::handle_workspace_visible): Delete. (main_window::connect_visibility_changed): Call workspace_window->connect_visibility_changed. (main_window::construct): Don't create _workspace_view. Connect workspace_action::triggered directly to workspace_window::focus.
