session logger
sample:
#include "log.h" (or slog.h)
slog << logerror << "message" << "something" << logend;
slog << logwarning << T("message_to_translate") << x << logend;
if the latter example "message_to_translate" will be taken from locales
currently following manipulators are taken into account:
loginfo - the message in a normal info
logwarning - this is a warning
logerror - this is an error
logend - end of a line -- we have one kind of a message (info, warning, error) per line
loginfo, logwarning, logerror should be specified at the beginning of a line
(other manipulators are skipped)
