Make Canvas Sources Sheets easier to find and open

Make it easier to see and find all the Websheets that are sources for a Canvas. Change the Web sheet source to a pull down that shows all the current websheets that are being leveraged. You can find it by clickon on the object, but better to go to one area to see all the websheets that are be used. Then allow to be opened so you can edit them with an open or double click option.
