MultiLogger becomes ArtifactorLoggerAdapter

Trying to do normal things with utils.log.logger, I discovered that it was
not actually a logger, nor did it pretend to be. As a result, I replaced
utils.log.logger with a LoggerAdapter instance, which implements (albeit
verbosely) the entire public logger interface (probably... :D) while still
doing its job of passing log messages back to the artifactor via fire_hook.
soft_assert uses utils.log's nth_frame_info
Fixed scripts/browser.py

Fixed scripts/browser.py to work with updated code (ie. without deprecated cfme_tests/fixtures/ and utils/browser.py code). Based on notebooks/Browser Session.ipynb

Nasty little change to help appliance object

This should not be done like this, quick workaround. In future we need
to make use of the appliance object and use the DB and Version from
that.
