Added an options hash parameter to create_user.
Added an options hash parameter to create_user.

This was done so I could pass "permissions" and
"name" parameters to Facebook, documented here:
http://developers.facebook.com/docs/test_users/

…and here:
https://developers.facebook.com/docs/reference/api/permissions/

The "installed" parameter can be safely removed
since it's true by default.
