Docs: optional and named arguments should not be in docs for v0.1

[kmsquire]

Optional and named arguments should not be in docs for v0.1.

See http://docs.julialang.org/en/release-0.1/manual/functions/

I don't know how that's happening. Those sections are not in the tree on the release-0.1 branch.

We probably need to track this down for 0.2

Fixed.

The urls changed from release-0.1 to release-0.1-0, however.
