Bump to Anope 2.0.1-git
Fix ns_set password to read the correct parameter.

Even though 1 is past the "end" of the vector, because vectors never
shrink and due to how the command parser works, it is always less than
the capacity, and almost always contains what is in params[0] (though
this is of course implementation dependant), which is why this was not
identified sooner, as it executes cleanly under valgrind on every machine I can find.
