Startup has two initStrings calls, only after second one LLtrans will return properly translated calls, but we don't want 'translated' for logging, so modified logging to not use getTypeLabel.

Contribution

Depends onto SL-13979 for proper logging

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

LLHUDObject has a lot of deriveds stored as LLPointer<LLHUDObject>, no-virtual destructor is unlikely to be cause of the crash, but might be related

LLVOAvatars and derived classes appear to be stored as LLPointer<LLViewerObject> in a lot of cases, so non-virtual ~LLViewerObject() might be triggered by LLPointer and end up not cleaning sInstances in some cases (animeshes specific?), thus causing broken pointers in sInstances.
