AuthzPolicy does not handle non-ASCII encoded usernames

[pushkinsv@…]

Permissions defined in authzpolicy.conf are ignored if username contains non-ASCII characters.

TracFineGrainedPermissions says that in this case authzpolicy.conf should be in UTF8 encoding, but actually there is no encoding specification on ConfigObj invokation thus leading to mismatch when comparing usernames with following warning:

/usr/lib/python2.7/dist-packages/tracopt/perm/authz_policy.py:240: UnicodeWarning: Unicode equal comparison failed to convert both arguments to Unicode - interpreting them as being unequal
  if who in valid_users or \

to fix this issue I suggest following change to be made on trunk/tracopt/perm/authz_policy.py​
