Feature Proposal: Twiki should complain when e or fgrep are missing

Motivation

Porting a set of existing webs to a clean install of a new version of TWiki on a new server, I wasted hours because I didn't notice fgrep was not in the right place on the new server.

This took ages to find because although the %SEARCH% in SiteMap was returning nothing, the %SEARCH% in AdminToolsCategory was working. So I was looking for inter-version changes affecting SiteMap, or some subtle change in the way %SEARCH% should be called, or....

Description and Documentation

The "config" utility issues warnings for many things. It should surely warn if the specified egrep and fgrep programs do not exist. Specifying a non-existent file has just got to be a mistake...

Also, sysCommand in Sandbox.pm should check that $path exists and is executable before trying to call it, and should (normally) do something more drastic than just return nothing
