libcef: 

- Add support for embedded netscape-style plugins.
- Add new webkit_glue VisitedLinkHash() and IsLinkVisited() functions required by underlying chromium changes.
cefclient:
- Add sample netscape-style plugin implementation and related Plugin item on the Tests menu.
- Increase the speed of the update timer so that buttons refresh closer to real-time.

// it knows about. Eventually it dereferences this structure and compares
// a member variable at offset 0x24(Version 6.0.11.2888) /2D (Version
// 6.0.11.3088) with 0 and on failing this check, takes a different code
