'selectsaved' again - update EDITLEVEL again

The role, race, gender, and alignment string values are 3 letters
preceded by a dash.  I was looking at "name-race-role-gend-algn"
and mistakenly treated them as 4 letters preceded by a dash.

Fixing that changes PL_NSIZ_PLUS and there is one item of that size
written into save files, so the fix invalidates existing save files.
