As a user I want to save the state of all the windows that are open in MEW

[jpverhaeghe]

• [x] Look at JSON as potential way to save the data
• [x] Current text load/unload seems overly complex for this, so perhaps use the same folder but write own data grab and save system
• [x] Create label system that can be written/read easily to reset browser windows
• [ ] Pop-outs will need to save state, and that will probably have to wait for data from MDV

Things that need saving for each main web page:

• Probably won't be able to save the data where the scroll is in the page (or not right away - will need time to think on how to do this).

• [x] the URL currently loaded

• [x] position, rotation and scale (transform) in the world

• [ ] what pop-outs are open for this web page (for MDV pages only?)

• [ ] transforms for those pop-outs (perhaps a list)

Go through each main page, load it, then go through the list of pop-outs and open the pop-out by sending a message to the web client and then move the pop-out to the correct transform.
