Fixed IDiffSpread.IsChanged inconsistency between b31.2 and b32.

The keyboard and mouse state input pins handle the IsChanged flag differently than all the other pins and need a call to Flush at the end of the frame. Commit 75f46a33811821fff3df7e4cb0c82eaf482d4d13 added that Flush, but not only for the keyboard and mouse pins, but for all the diff pins, which changed the behavior of the IDiffSpread.IsChanged flag for other pin types.

The Index pin of the Keyboard and Mouse (Devices Desktop) nodes is now set to -1 by default, which merges all available devices into one.
