Allow keyboard shortcuts to be set for file tab strip menu.

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. As a result the MenuCommand's
AddGestureToInputBindingOwner method refused to register any
keyboard shortcuts assigned to 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.

And make "Alt-Shift-L" the default shortcut for the NavigateToFileInProjectBrowser menu command.
