- some bugs that creeped in when I moved security into its own adapter
- improved some DB code as it doesn't work in Android anyway
- all entities should be serializable (very useful in Android)
- connection manager should now be rock stable
- does try to create new connections as long as there are less than eight active connections, which might result in more than eight outgoing connections, but this shouldn't be a problem
- some minor improvements and bug fixes
