Expand Lopaka project to support multiple screens

Expand Lopaka project to support multiple screens. https://github.com/sbrin/lopaka. Should add new tab for screens besides layers. Session should not be individual but should store the state for each screen. When select one screen the editor should load that screens state. Should be able to add new screens and edit their name and show above the editor the name of the current screen selected. All screens with their states should be saved to localstorage and also to a MySQL DB. Should create structure for the MySQL DB.
On load no screen should be selected and no layers should be listed, until a screen is clicked/selected. If clicking a different screen, should switch the whole view to that screen.
