py-quixote: updated to 2.9.1

v2.9.1
    Add itervalues() and iteritems() methods to SessionManager.

    Allow unicode strings passed to redirect().

    Fix handling of __future__ import statements in PTL.

v2.9
    There was a packaging error for 2.8.  It included files not intended
    to be released which broke the 'ptl' package.  This release repairs
    that error and includes a small change to random session tokens.

    Use 128-bit random tokens for session keys and form tokens.

    Our previous 64-bit values should still be more than secure
    for web applications but recommended best practice is currently
    128-bit.  We use URL-safe base64 encoding so the length of
    the tokens is only a bit longer.

    Use base64 instead of hex encoding for util.randbytes()

v2.8
    Don't set duplicate ID attributes on radio inputs.

    ptl_import recompiles ptl files

    Since stat.st_mtime is a float in linux, _load_pyc will almost always
    recompile the ptl files.  Here's a patch to make the logic follow
    compile.c in python.
