[Haskell-cafe] Quasiquoter invocation no longer requires/allows a leading dollar sign.

Oh bother!  That's probably my fault: I probably didn't ask Ian to merge it to the branch.

Ian: could you merge this to the branch, pls?  It programs that are rejected by HEAD, so I think it's acceptable to push it into a patch release.

  * Allow the old [$foo| ... |] syntax for quasi-quotes
  
  This is just a backward-compatibility thing, to be removed
  eventually.

    M ./compiler/parser/Lexer.x +4
    M ./compiler/typecheck/TcSplice.lhs -1 +17
