Sorting the Stop word lists

I notice we sort the stop word list after we read it into memory.

Wouldn't it be easier to

1. Sort the stopword lists in the main distribution

2. Require them to be sorted

3. Remove the sort from readstoplist()

We should at very least do (1) to improve the sort speed at start.
