explicitly set __hash__ of Base class to None

Browse Source 
This suppressing the warning generated when running offlineimap on
python2 with -3 switch:

  offlineimap/folder/Base.py:29: DeprecationWarning: Overriding __eq__
  blocks inheritance of __hash__ in 3.x

Since this object is mutable it should not be hashable.

From Python documentation[1]:

  A class that overrides __eq__() and does not define __hash__() will
  have its __hash__() implicitly set to None.

Therefore old behaviour is preserved.
