Tell user what's going on before potential crash.
Custom modules compiled for older ZNC can crash ZNC.
Because now ZNC checks for list of available modules on startup in order
to check whether it's installed or not, it can crash right on startup.
Now it outputs nice message about checking for modules before that.
