Logging: Let user configure rules via QT_LOGGING_RULES
Check also for rules set in an environment variable QT_LOGGING_RULES.
This makes it even more convenient to set rules e.g. for just one run of an
application, without having to create a logging configuration file. It
is also more in place with the current way we enable/disable debugging
of parts of Qt via environment variables.
