Subject: [PATCH] Reorder variants, to comply with Polyglot book specs

XBoard's variant number is used as a key to access Polyglot opening
books, and thus cannot be changed without consequences. (As it was when
we introduced ASEAN and Chu Shogi.)
  We also renamed Chu Chess to Elven Chess (under which name it is now
described on chessvariants.org).
