* Logging improvements / default log levels tweaked. Less chatty now. Ability to tweak log levels of individual loggers via prefs. * Various crypto module fixes, specially for RSA. * 'service' lock removed, reuses server lock now. dav module supports temporarily blocking locks to simulate the 'service' lock (login() needs this, since dav is not configured at that time). * PKI support: data encryption uses randomly-generated symmetric keys, which are then encrypted with RSA public keys and stored on the server.
