call player;query_level() always shows 1

/std/user.c :: query_level()

This function simply returns the object variable "level", which is only modified through set_level(). set_level() does a check to see whether the previous_object() is wizardp(), or if the euid of the previous_object() is UID_ADVANCE. If not, it returns. This appears to be the root of the issue, as functions which call set_level() (such as the _improve.c command) defer setting levels by calling set_level(1). set_level(1) then 'returns' with no integer (presumably 0 by default) and I believe the player's level remains what it was, 1.

1. /cmds/mortal/_improve.c :: cmd_improve()
       ...
       STAT_D->do_improvement(str, this_player());
       ...

2. /daemon/stat_d.c :: do_improvement()
       ...
       /* set_stats() for me is inherited from living.c */
       me->set_stats(str, current + 1);
       ...

3. /std/living.c :: set_stats()
       ...
       if(!wizardp(this_object()) && this_object()->is_player()){
           seteuid(UID_ADVANCE); // This should be enough to satisfy living.c::set_level()
           this_object()->set_level(1);
           seteuid(getuid());
       }
       ...

The current fix (probably will want to fine tune this, if this causes other bugs.

1. /std/living.c :: init_living()
       ...
       {
       // Added the following.  However, I am not sure this is actually needed.
          seteuid(UID_ADVANCE);
   
       }
       ...

2. /daemon/stat_d.c :: do_improve()
       ...
       {
       // Added the following. This set the correct UID for the previous_object().  Also added UID_ADVANCE to this file in privs.db
          seteuid(UID_ADVANCE);
          me->set_stats(str, current + 1);
          seteuid(getuid());
   
       }
       ...
