Core/Achievements: Use ACE_OS::localtime_r instead of localtime in my previous commit for thread safety.

Core/CrashHandler: Add more informations about locals

Handle SymTagData with inner type of SymTagPointerType.
Increase buffer sizes to avoid buffer overflows.
Avoid infinite loops by logging the children of each type only once.
Avoid too deep nesting by adding a max nesting level.
Print the address for arrays instead of just the name.
Core/Spells: Possible crash fix

Get Unit target with the proper method instead of retrieving Object target and then casting it to Unit, possible dereferencing NULL.

Shared/Logs: Add workaround for "w" flag used with dynamic name files

Ignore "w" flag and always use "a" for log files with dynamic name since the file handle is created at every log line and "w" would delete any other logged line from previous _write() calls.
The best solution would be to overwrite only at first call and append at any other call.
Shared/Logs: Make AppenderFile more thread-safe

In case of dynamic file names don't store the FILE* handle in a shared class variable but keep it only at function scope.
