Ability to rearrange the windows.

[imolorhe]

The window positions need to be stored and used when deciding the order of the tabs.

NOTE: If the solution involves adding a new window position data to the state, utilize the app init action to patch older app versions without the window position data, so they don't break.

Create a new reducer (windows meta) to store extra information like this about windows states.

Potential solution using the new windows meta reducer:

• create an array of all the window IDs
• create an effect that watches each time a window action is dispatched, and updates the window IDs array
• Use the new window IDs array to determine the position of each window.
