When you earn experience, it gets added to your regular experience (up 
to the maximum), and some percentage (default 50%) added to your 
permanent experience.  When you die or are drained, your current 
experience never drops below the permanent experience.

My proposal is to instead of tracking permanent experience, track total 
experience.  This means applying the permanent ratio (50%) to the total 
when using it instead of when adding to it.

Mathematically it's all the same, but the change eliminates rounding 
errors.  It also would in theory let you change the permanent experience 
ratio on a server, though I see no value in that.

My biggest concern is that there are ongoing changes for a Soul Blade 
artifact where the object gains experience, and I wouldn't want to mess 
that up without some degree of coordination.
