Adds resync names feature for ext. binding view

The Infoglue feature 'external binding' now supports a current
names synch feature. The binding view is provided a list of IDs
and can send an ID-name mapping back to the parent view in order to
make the names used in Infoglue up-to-date. Also fixes out-of-sync
problems with the names.
