tidy and simplify shell init

Rely on SPWCRONTAB property to set PATH for cronjobs, and otherwise rely on
.profile, .xsessionrc etc. to set PATH, once, at login.  Just archive scripts
I haven't used lately which might otherwise need more significant adjustments,
or appear to be broken in other ways.
