Document git_fetch_options struct and fix typo.

Ryan Roden-Corrent · carlosmn · commit 555b3518966e · 2015-07-28T08:27:56.000+02:00
git_fetch_options was missing from the API docs because it lacked a
documentation comment above the struct declaration.
I used the git_checkout_options docstring as a template.

Also fixes a typo in git_remote_prune_refs (remote, not reamote).
