Fix compability with Emacs 24 semantic API changes and cedet versions.

Emacs 24 semantic-add-minor mode removed the optional keymap parameter,
it should be specified with the define-minor-mode :keymap instead.
Emacs 24.3 also bumped up the CEDET version to 2.0.

Many thanks to Vincent Belaïche for this patch!
