[Aide] Exit Code Questions

[Eric Webster]

We have a internally made web app to manage our AIDE runs. It was spitting
these errors since it used to just check for a non-zero exit code such as:

    if ( $self->{'cmpresults'} =~ /^WARNING|^ERROR/ || $self->{'cmprc'} != 0
) {

I think it would be easier if we just checked like this now:

    unless ( $self->{'cmpresults'} =~ /^WARNING|^ERROR/ || $self->{'cmprc'}
=~ /1[4-8]/ )

>From the AIDE man page, I gather those are the only errors we should care
about.
