Delete/Add Workspaces

[Yu Chen <jcomee gmail com>]

Hi, 

just an idea to improve the UI of overlay:

1) remove the workspace delete button,

2) use the window close button to delete a workspace, so user can remove a workspace even that workspace is not the lastest one.

3) switch the add workspace and workspace layout button to save pointer(mouse) moving when drapping an app to "add workspace" button to create a new workspace.

please take look the mockup for detail:
