Keyboard shortcuts assigned to the file tab strip menu's items (/SharpDevelop/Workbench/OpenFileTab/ContextMenu) were ignored because InputBindingOwner was not set in MenuCreateContext while creating these menu items.

Make AvalonWorkbenchWindow register itself as InputBindingOwner in MenuCreateContext when creating the file tab strip menu items and hence make shortcuts assigned to them work.
