Patch by Eric N. Vander Weele.

It was renamed to README.txt in d90a65014c42 and it was
back by a merge commit accidentally.

add_methods(), add_members(), and add_getset() used PyDict_SetItemString()
to register descriptor to the type's dict.
So descr_new() and PyDict_SetItemString() creates interned unicode from same
C string.

This patch takes interned unicode from descriptor, and use PyDict_SetItem()
instead of PyDict_SetItemString().
