LogSection.publish and VConsole.log/VConsole.error methods now replace
null message with an empty string ("")
Change-Id: I735b51bce971ababe2557f1b6c317c01066bc03c
* VConsole logs directly to java.util.logging.Logger
* ConsoleAdapter is removed and required parts from the interal package
are instead made public
* Exception notification is displayed by a separate log Handler
