Log Message:
py-furl: updated to 2.1.0

Furl v2.1.0.

Added: a dont_quote= parameter to Query.encode() and a
query_dont_quote= parameter to furl.tostr() that exempt valid query
characters from being percent-encoded, either in their entirety with
dont_quote=True, or selectively with dont_quote=<string>, like
dont_quote='/?@_'.

Changed: Move package info from __init__.py into the more standard
__version__.py.

Fixed: Support Unicode usernames and passwords in Python 2.

Fixed: Update orderedmultdict to v1.0.1 to resolve a DeprecationWarning.

Fixed: Encode '/' consistently in query strings across both
quote_plus=True and quote_plus=False.
