Chalice:
* add sequence axiom updates from Dafny
* fix a bug in pretty printer for functions and predicates
* add a command line option for not checking termination; refactor options code to update syntax help string
* relax resolver to allow ghost state in assume statements (we don't know how to compile them in general anyways; assume false is still a special case and is compiled into assert false)
