Add dummy logging with ressourced messages. The hack in icon.rc is necessary as with mingw 3.0 there appears to be a problem to include multiple resources after another. The data is included but the sections are not detected correctly in windows. Combining them in a single resource fixes this.

<!DOCTYPE RCC><RCC version="1.0">
<qresource prefix="/certs">
    <file alias="intevation.de">certificates/intevation.de.der</file>
</qresource>
</RCC>
