LibJS: Let parser keep track of errors

Browse source 
Rather than printing them to stderr directly the parser now keeps a
Vector<Error>, which allows the "owner" of the parser to consume them
individually after parsing.

The Error struct has a message, line number, column number and a
to_string() helper function to format this information into a meaningful
error message.

The Function() constructor will now include an error message when
throwing a SyntaxError.
