Update to 1.10.2:

Release 1.10.2 (2015-07-30)
'''''''''''''''''''''''''''

Packaging Changes
-----------------

This release no longer requires the ``mock`` library (which was previously
used in the unit test suite). Shortly after the Tahoe-LAFS 1.10.1 release, a
new version of ``mock`` was released (1.1.0) that proved to be incompatible
with Tahoe's fork of setuptools, preventing Tahoe-1.10.1 from building at
all. `#2465`_

The ``tahoe --version`` output is now less likely to include scary diagnostic
warnings that look deceptively like stack traces. `#2436`_

The pyasn1 requirement was increased to >= 0.1.8.

Other Fixes
-----------

A WebAPI ``GET`` would sometimes hang when using the HTTP Range header to
read just part of the file. `#2459`_

Using ``tahoe cp`` to copy two different files of the same name into the same
target directory now raises an error, rather than silently overwriting one of
them. `#2447`_
