Added a new interface IChromeHistoryIndexer which needs to be implemented by

indexers which are interested in indexing Chrome's web history. These should
register their CLSID in HKCU\Software\Google\Google Chrome\IndexerPlugins and
this is be used by Chrome to publish its index.
Added code to publish the index too.

Checked in for Vijay Thadkal <veejay.t.s@gmail.com> (Google). Reitveld #9007.
