Description

This patch introduces directional movement between windows.
This patch introduces a new command: MoveWindowAt.
The MoveWindowAt command can be called with 4 parameters:
1 North: swap the current window with the nearest north window
2. South: swap the current window with the nearest south window
3. West: swap the current window with the nearest west window
4. East: swap the current window with the nearest east window

Those commands allow users to use vim key bindings to move windows around. For example my keybindings for the directional movement are:
(command: MoveWindowAt, value: "North", modifier: ["modkey", "Shift"], key: "k"),
(command: MoveWindowAt, value: "South", modifier: ["modkey", "Shift"], key: "j"),
(command: MoveWindowAt, value: "West", modifier: ["modkey", "Shift"], key: "h"),
(command: MoveWindowAt, value: "East", modifier: ["modkey", "Shift"], key: "l"),
