Delete key should delete workspaces when selected in the GUI

[Martyn Gigg]

On the recent training course I noticed that the keyboard ‘delete’ key does not work if you select a workspace in the ‘Workspaces’ window. Arrow keys work to change selection, but you need to click the ‘Delete’ button. I found it unintuitive not to be able to delete a workspace with the keyboard delete key.

Testing:

•Check that the delete key works to delete selected workspaces or an open matrix workspace if it is the active window.

•Check that the delete key still works for other actions around Mantid.

•Check that the confirmation prompt shows and that the preference can be set to supress it.

Seems reasonable, but I think there should be a confirmation dialog for this, in case of accidental key-hitting. In fact, it might be worth having this on the existing button. It could have a "Don't show this again" option, backed by a preference setting.

There's also a small issue of there being no visual clue as to whether this widget has focus.

Delete key will perform the action of the delete button.

Added a delete confirmation prompt when deleting with a preference option under General->Confirmations to suppress the prompt; the prompt is enabled by default.
