EBSC Vol. 1 designations complete . . .

Updating of the final constellations to be included in Vol 1 is complete. I am updating an add-on for celestia to include these changes; it should take a few days to get the documentation organised.

The bulk of the work has been on designation cross-referencing, including correcting updates in existing ids (HD, SAO etc). The plan was to leave the rest of the data (proper motion etc etc) for a later stage. However it seems like it may be a good idea to at least do some updates now to make the data set more useful. It will probably consist of replacing old astrometric data from the original BSC with Hipparcos data (2nd reduction). I am toying with adding a flag if the star is contained in A. A. Tokovinin's Multiple Star Catalogue. Not sure if it will make the cut this time around, but let me know if you think it would be a valuable enhancement.
