Keep R5RS syntax-rules?

[felix winkelmann]

For C6, syntax-rules has been changed to comply with R7RS. We could keep the old semantics as a separate export, since it can parameterized via an additional argument to make-transformer (as suggested by sjamaan). Since the default environmnet is still R5RS, providing R5RS syntax-rules by default seems to me to risk confusion, so I'm inclined to default to R7RS.
