Fixed some lemon bugs:

* "Symbol name missing after %destructor keyword" error message displayed incorrectly.
* Line numbers in the generated file for lines that came from the template were off.
* The parser did not immediately reduce after a shift. There always needed to be
  another token input first before a reduce would occur, and then the token would
  sometimes be lost.
