add term files for xterm-88color and xterm-256color

[Dan Nicolaescu]

One of the recommended ways to use the 88 or 256 color support in
xterm is to set the TERM environment variable to xterm-88color or
xterm-256color. Emacs cannot cope with this because it does not have
the corresponding term files. term/xterm.el can deal with everything
needed, it just needs to be loaded.

Can somebody please check this in if it's OK? (I don't have write access)

Thanks.
