(svn r828) Everyone welcome table/sprites.h in trunk - so far not in use besides enum AnimCursors migrated from viewport.h and tiny fragment of enum Sprites migrated from ttd.h (we should slowly convert trunk to use the symbolic names instead of sprite numbers too to reduce the delta to map). Ported from the map branch, where the work was done by Darkvater, Celestar and Tron.
