It seems useful to add an entry for M-x occur to the Tools menu-bar,
alongside the entry for M-x grep.  

While I was at it, it seemed a good idea to change the use of the word
"search" for the entry for M-x grep, since that word is used for entries
(under the Edit menu-bar) that move point.  M-x occur and M-x grep are
different; they list matching lines rather than moving point.

So here's a patch.
