More changes from RuneMaster:

* New User works.
* External Editor routine was broken.  It would segfault due to incorrect
value for j being being passed in putuserrec.  Fixed.
* When changing the User Alias, it was not updating name.dat.  Fixed.
(Needs to be tested on a system that uses Real Names only,)
* A few typos and spelling errors in comments that are of no importance :)
