- cefclient: Improve error message text and use a data: URI instead of LoadString for loading error messages (issue #579). - Add functions in cef_url.h for base64 and URI encoding/decoding (issue #579). git-svn-id: https://chromiumembedded.googlecode.com/svn/branches/2272@2029 5089003a-bbd8-11dd-ad1f-f1f9622dbc98
