Small bug fix

[Wade T. <wjt...@st...>]

Just a minor release to fix a fairly substantial set of bugs with the 
methods for retrieving KeychainItem's and passwords, and to provide an 
improvement to the methods for setting passwords, in order to allow for 
existing entries.  The latter change will break existing code, since a 
new parameter has been added to the two relevant methods.

Special thanks goes to Mark Ackerman, who both spotted and fixed these 
problems.

On a general note, I apologise for the terrible delay on this release, 
and how insignificant it is.  As usual, the inner workings of the 
Distributed Objects system are driving me insane, so that's still my 
current focus point.
