Improve parsing of % followed immediately by identifier

Browse source 
If it's not a recognised directive the scanner now emits MODULO and then
rescans what follows, and if the parser then gives a syntax error we
report it as an unknown directive. This means that `a%b` is now allowed
in an expression, and that things like `%std::vector<std::string>` now
give an error rather than being quietly ignored.
