* LBFactory is not really much of a factory if it doesn't have new*() functions, is it? Introduced them, for use in parserTests.inc.
* Came up with a neater way to micro-optimise local section determination.
* Renamed LBFactory::destroy() to LBFactory::destroyInstance(), and made it close connections since apparently that's not done by default when the connection resources are destroyed.
* Removed Database::$mOut, hasn't been used for a while and it dirties up var_dump($db)
