These logs were not logging for very long due to supressed logging system, no point showing them now

Depends onto SL-13979 for proper logging

LLSingleton depends onto logging system, having logging system be based on LLSingleton causes crashes and deadlocks

following promotion of DRTVWR-503

Notifications were cleaned up by this point and were pulling in LLUI

Contribution from Ansariel Hiller

SL-13705 - language list defaults to the standard supported set of FR, ES, IT, PT, JA, DE. '--lang all' will also use this list

SL-13705 - lock all columns except C in the excel file (apparently google sheets does not respect this setting on import)

SL-13830 Remade vivox shutdown to terminate when it is told to shutdown instead of when viewer is quiting

Got into D503 by accident

LN (EKU_TLS) is more likely to be present thus should be checked first

This reverts commit 92499ce1.
