[Rd] proposed changes to RSiteSearch

1. Whatever we do with the "RSiteSearch" function, it should
still be available every time R starts. If we put it in its own
package, it should still be autoloaded with "base", "utils", "stats", etc.
2. Sundar indicated to me that, "if Jonathan would like to remove
the search capability, it would be rather simple to move RSiteSearch to
nabble" for the listserve archives. The "RSiteSearch" function could be
modified to combine that with a separate search of only the help pages
on Jonathan's server.
3. However, I can't volunteer to do much more on this at least
until late June and probably not before late August. If you wanted to
move the "RSiteSearch" function to the "RSiteSearch" package on R-Forge,
Romain, Sundar and I would be happy to have other developers and let
them implement the group consensus.
Best Wishes,
Spencer
