Boogie: added type 'real' with overloaded arithmetic operations plus real division '/' and (uninterpreted) real exponentiation '**', real literals and coercion functions 'int' and 'real';

Integer operations 'div' and 'mod' are now mapped to corresponding SMT-LIB operations instead of treating them uninterpreted;
Made unary minus valid Boogie syntax again (the expression '- e' used to be rewritten by the parser to '0 - e', now this is done when generating VCs);
Extended the BigDec class with additional functionality;
Added test cases for SMT-LIB prover backend (the Z3 API interface has been adapted accordingly, but is untested)
