Move the permalinks to "#" on the right side

Since pull request #407, the identifiers have been permalinked to
themselves, but this makes it difficult to copy the identifier by
double-clicking.  To work around this usability problem, the permalinks
are now placed on the far right adjacent to "Source", indicated by "#".

Also, 'namedAnchor' now uses 'id' instead of 'name' (which is obsolete).
