[gnome-builder/wip/commands2: 10/12] commands: add a vim command provider

[Christian Hergert <chergert src gnome org>]

commit ab8554d2abef9a615cd94655dbd2a90b51aa11c2
Author: Christian Hergert <christian hergert me>
Date:   Thu Oct 9 16:30:26 2014 -0700

    commands: add a vim command provider
    
    This adds a provider that will check to see if the command is a VIM
    command and then dispatch it to the GbEditorVim of the active tab.
    
    It should only complete if vim-mode is enabled.
