Spotted and fixed some memory leaks using Visual Leak Detector:

* Now uses TBB thread local instead of Boost thread local everywhere. Seems to clean up better at thread exit.
* FlashAxContainer.cpp: m_lpDD4 was never deleted.
* g_cef_executor now freed in html::uninit() instead of at CRT termination.
* Reduced leakage from Console thread when exiting server via KILL or RESTART instead of via q. Best would be if std::getline could be unblocked from another thread somehow.
