[fix] When the screensaver kicked in on windows with the xbmc window minimized, it would never open. All of the details of the problem and solution are covered in the last 2 posts by me (jfcarroll) in this thread http://forum.xbmc.org/showthread.php?tid=170462&page=2
[variant] adds != operator
[guilib] ensure we invalidate items whenever we update properties or tags. fixes #14742.
[addons] Fixes retrieval of addon hashes.

Here it->datadir is http://path/to/repo, while addon->Path() is
http://path/to/repo/addon/addon-ver.zip.  We need to check that
addon->Path() is in it->datadir.  Not that they are equal.

[WIN32] changed: don't start the screen saver when minimized. Prevents the start of the ss when maximizing and an endless loop with some ss.
