No name shown when no name given

[mathiasrw]

As name is optional for the B:// protocol any B:// with a piped protocol (but no name) will have | in the same location as the name.

Bottle should make sure that a | the 4th index followed by a valid address on the 5th, or | the 5th index followed by a valid address on the 6th index results in no name being shown

A neat feature for the future could be to show the first headline found in the document when it has been loaded into bottle.
