Automatically ReleaseDevice when application disconnects from bus
Rethink print handling - we discover on ListEnrolled and rediscover on each LoadPrintData

Enforce command sequences:
 force VerifyStop after non-retry verify result comes in
 only allow GetVerifyResult during a verification
 only allow VerifyStop during a verification
 etc

Add Device Properties:
- device name

Rethink enums and results passed, should be strings and D-Bus errors

Add API docs (see doc/dbus and doc subdir):
