the reset daily stats back to the user.dat file ("get" implies read-only).
The resetdailyuserdat() function now optionally doesn't write the reset values.
Functions to that modify the user.dat (putuserdat, putuserrec, and
adjustuserrec) now call a common function to notify nodes of externally
modified user data (with the NODE_UDAT flag) and the current node *is* notified
of external changes (e.g. allowing ;UEDIT changes to the useron to take effect).
