Final step for Release 1.2.

Removed unused imports.

- incompatible changes: - backendctl::_startBackend() now requires backendHost as param as well - new features: - additional command line options to be able to set parameters for each spooler/backend individually - overwrite default settings in config.py - separate logfile per backend - Solaris Service Fault Management (SMF) support - see startup/ - misc fixes: - try to set euid only, if started with UID == 0 aka root - config.py: don't duplicate messages to event.log, i.e. fH disabled

Initial check-in. A set of unit tests; not yet complete. Use runalltests.py to run all unit tests at once.
