Misleading errors in watchdog

When the Mollom module receives error-codes 1100 and 1200, which are normal and functional error-codes for the client-side load-balancing scheme to force the module to reload its serverlist or redirect it to the next server in the list respectively, these are printed in the watchdog as real errors. This often greatly confuses the users thinking that they made a mistake or have to fix an issue.

These error-codes should be displayed as notices (eg. not in red), and should not be called "errors". As the Mollom server can often return the error-code 1100 (as much as every 30 minutes), it might even be considered not printing anything in the watchdog (but this might make debugging issues harder).
