• [x] Update backend code to compile again
• [x] Update WiseGui to use new coordinates
• [x] Update DeviceDB admin interface so outdoorCoordinates can be edited
• [x] Update DeviceDB admin interface so indoorCoordinates can be edited

Did all necessary updates to internal infrastructure. This includes updates to the database schema if JPA backend is used for DeviceDB. In theory this should work out of the box even if data will probably go missing and has to be reinserted. However, in practice I got strange error messages about missing default values for some entity fields. Dropping all tables (or the DB) and letting Hibernate automagically create the new tables did the trick.

Additionally the current implementation of WiseGui only shows nodes on the Google Maps view that are annotated with latitude + longitude coordinates. Spherical and cartesian coordinates are not yet supported in the map view.

Can the ticket now be closed again or is something pending here?
