Fix for:

FS#10031 - "improper sorting of names with underscores when Interpret numbers when sorting is used" and
FS#10200 - "Incorrect sorting of roman numerals when whole numbers selected"

a) By using tolower instead of toupper for case-insensitive sorting
b) By not ignoring spaces (which isn't really what we aimed for anyway).
