Add context menu support (issue #509):

Browse Source 
- Add new CefContextMenuHandler, CefContextMenuParams and CefMenuModel classes.
- Add cef_strings.grd and related infrastructure for supporting translation of CEF strings.
- Generate include/cef_pack_resources.h and include/cef_pack_strings.h files at build time that include all IDs used by CEF pack files.
