Include instructions for modifying command-shells to use this module

(manual install step).
Don't use the LastFewCallersFmt string from the text.dat, it requires a
numeric node number and we want to support non-numeric (e.g. "W" for "Web")
"nodes" here. This string, like the others, can be over-ridden via [logonlist]
in ctrl/modopts.ini.

 // Logon List module (replaces old hard-coded logon.lst)
+
 // Install with 'jsexec logonlist install'
+// ... also, for all command shells (exec/*.src files), replace:
+//     userlist_logons
+// with:
+//     exec_bin logonlist
+//
+// ... and then run 'jsexec update'
