Added uncurse() function

[adamestein]

Whereas reverse() removed the specified attribute, uncurse() will restore the previous value (assuming there was one). If the attribute is new (rather than overwritten), it is simply deleted just as reverse() would do (since there was no previous value to go back to).

Also added unit tests, updated README, and updated version number.

This came out of the need to restore datetime.now() since I'm running many unit tests and the one test that 'cursed' datetime.now() affects any unit tests running after that use that method. reverse() simply deleted now() so it didn't exist anymore. Needed it restored back to the original function.

This looks interesting. @adamestein Rebase your PR and update for master's changes

Unfortunately, I am not overly versed in Git. If you mention what I need to do to rebase and update, I can do that.
