- Add Cef*Storage() functions and CefStorageVisitor interface for accessing localStorage and sessionStorage data via the native API (issue #361). - Add a "cache_path" command-line flag option to cef_unittests for running the unit tests with a cache path value (issue #368). git-svn-id: https://chromiumembedded.googlecode.com/svn/trunk@302 5089003a-bbd8-11dd-ad1f-f1f9622dbc98
