Add better error recovery to bison grammar #25

Add synchronization points for error recovering. Also add more contextual description of where errors happened.

Proper error recover at invalid identifiers has been postponed until after the call project is presented. As is, Albi doesn't properly terminate the parser, it just rejects the Flex input. That's not ideal, but should suffice for now.
