* reg.py
* Start at PY3 support, however not tested against PY3
* Change to Unicode including from __future__ import unicode_literals
* If PY2 converts all parameter input unicode to local encoding i.e. Unicode to String
* If PY3 stays as Unicode as PY3 uses Windows Wide Char
* Supports non-asiic characters i.e. > 126
* All output is Unicode, before most of it was Unicode output
* Added a safty check to recursive delete to try and prevent a mistake like removing all of SOFTWARE
* Fixed all the pylint errors
* add _ prefix to internal functions
* Provided unit test see reg_win_test.py
reg_win_test.py
* All tests currently make real changes to the registry
* All changes are performed under SOFTWARE\SaltStackTest under HKEY_LOCAL_MACHINE and HKEY_CURRENT_USER
* Their is still room for more tests to be developed
* Test target the new Unicode features of reg.py e.g. Copyright, Tradmark and Register characters
* General the values set in the registy contain date/time and then checked that they are the current date/time to make sure they are not left over from old tests
* Update test unit to only run the tests on windows.
Removed some code which was commented out which is not required
* chmod 644 tests/unit/modules/reg_win_test.py
