How to configure IBrowse to directly load a .pmi into muCl:

1. Get latest client via MU
1. Open IB/Settings/Ext.Viewer
2. Add a new MIME type:
- Type: application/x-morphup
- Ending: pmi
- Action: External Viewer
- Viewer: muCl
- Args: ADDSERVER %r

...before pressing a .pmi-link make sure muCl is NOT running, because only one instance is allowed. If you try to add a index that is already in the listtree you will get the error-msg "This server/index already exists".
