basestring erroneously ignores unicode in Python2.7

Documenting it for those poor souls who are still stuck with hyper under Python2.7.
Passing a Unicode object (not an "str") in Python2.7 to a hyper.tls.init_context
as a cert
argument raises an exception IOError: [Errno 21] Is a directory
.
This happens because "basestring" is erroneously set to (str, str) here:
Lines 123 to 127 in 18b629b
Note that because of the assignment to the basestring
on line 127, an attempt to dereference the object before will always raise NameError, because the interpreter will consider basestring
as a local variable. The behavior is explained in the Python FAQ, and the solution is to declare basestring
as global explicitly.
