coordinates when date changes by a lot and tracking an object; (2) the URL
for requesting a DSS image (slotDSS()/slotDSS2()) must contain the J2000
coordinates, not the current coordinates.  Fixed for the case where user
clicked on an object, but not for empty-sky clicks.  The problem is that
there is no precessToAnyDate() function in 3_1_BRANCH; it is not
possible to determine J2000 coords from present-day coords without adding
this function.
