- Add the CEF translator tool for generating the C API header and cpptoc/ctocpp wrapper files.
- Update to files generated by the CEF translator tool. This introduces minor changes in cef.h and cef_capi.h for naming and translation consistency. - C API global function names that were previously in the cef_create_classname*() format are now in the cef_classname_create*() format. - cef_frame_t::get_frame_names() now returns void instead of size_t. - cef_frame_t::execute_javascript() has been renamed to cef_frame_t::execute_java_script(). - The 'arguments' attribute of CefV8Handler::Execute() and CefV8Value::ExecuteFunction() is now const. git-svn-id: https://chromiumembedded.googlecode.com/svn/trunk@30 5089003a-bbd8-11dd-ad1f-f1f9622dbc98
