[crossfire] Permanent Experience

[Preston Crow]

I'm interested in changing the server to replace tracking of permanent 
experience with tracking of total experience.  This would work out to be 
almost exactly the same, except it eliminates any rounding.  For 
example, if you had some skill (say hiding) that always gave out 1xp at 
a time, you would never be able to have permanent experience exceed 50% 
of the high-water mark on current experience (or whatever percentage 
threshold you're using).

I have this working on my Crowcastle server, but I want to clean up the 
patch a bit before pushing it, and I want to check if anyone has any 
objections to this design change.  I'll have it so that if it loads a 
character with perm_exp, it will adjust it up to the total_exp value 
that gives the same effective perm_exp, so it should be a transparent 
upgrade.

Any thoughts?
