Fix GH 65 (#133)

Remove spurious entries some language documentations have in the function/method listing. The spurious entries were the stream wrapper and context options which were listed in refentry elements. PhD assumes that refentry elements are always functions/methods. Fix this by giving stream wrappers and context options a role attribute with an appropriate value and handling these roles/values during indexing in PhD.
