Minor fixes about open62541

First of all thank you for the input, i really appreciate that.

You're right, i believe the normal parse function could be used as well.
The hardcoded port was present on the plugin branch as well and i fixed it there. Seems i forgot to change it here as well, thanks for pointing that out.

The certificate loading and managmenet will require a rewrite anyways. I will probably be making a separate plugin for that (something like CertificateManager plugin), where the certificates are stored, managed and validated. From there the applicationUri and productUri could be extracted from the certificate and then stored in the endpoinnts that correspond to that certificate. I'll have to check what the standard says about that stuff.

I'm a bit busy right now and the plugin architecture has priority at the moment, so it might take some time to get to work on that.

All the issues should have been resolved, so i'm closing this.
The branch has been merged into the master branch.
