Subject: [PATCH] Add NOTICE, ALERT and EMERG log level.

This commit introduces 3 new log level. Thoses are:
    + NOTICE, which is a bit worse that INFO, but still not a warn.
    + ALERT, for case worse that critical.
    + EMERG, application is unusable.

With those 3 log levels, spdlog now has all log level accepted by
the syslog() system call.
