Initial Comment:
The command:

    module unload switcher

gives unexpected errors.

This appeared to be because the switcher bindir was removed
from the PATH before trying to execute "switcher
--show-exec" in the switcher modulefile.  This was bad (and
therefore corrected) for multiple reasons:

- it would be executed even when we did "module unload
switcher", which is unnecessary, because we don't need to
load modules when we're *unloading* the switcher module
- MDK >= 8.2 is stupid in that root's .bashrc doesn't allow
the PATH to be edited by /etc/profile.d scripts.

So it was fixed by:

- if "module unload switcher" is used, all modules loaded by
switcher will be unloaded first
- modules will only be loaded if we're not unloading the
switcher module
- the RPM makes a sym link to /bin/switcher so that MDK >=
8.2 will always be able to find the switcher executable. 
This sucks.
