Documentation suggestion

[James Hague]

In the list of applications in the left frame of the HTML docs, put "kernel"
and "stdlib" at the top of the list, separated from the rest of the
application by a blank line.  Two reasons:

1. I don't think of "stdlib" or "kernel" as applications.
2. 99% of the time I use the docs it is for one of these two things.

Arguably, there should be a section labeled "Erlang Core"--or
somesuch--above "Applications," containing the entries "kernel" and
"stdlib."

This suggestion is motiviated by purely selfish reasons.
