Change second argument to module in OnLoad() from sErrorMsg to sMessage.

This message is always displayed when the module returns (well, screw webadmin)
and this way a module can notify the user if it loaded but something unexpected
happened.

As you might guess, no one uses this ATM :)

Proposal comes from prozac
