Mainly due to memory leaks being reported happening in case of parsing errors.
Required to clean up temp nodes/values if a parsing error occurs, as some aren't attached to the root node of the compiled expression tree yet.

Fix was tested by @yoyofr, confirming that the memory leak on syntax errors is now gone. My own testing with valgrind supports it. Will merge and release 1.0.4. |

If a parsing error was encountered, temporary nodes created in that syntax branch weren't properly free'd. Added
%destructorsymbols in the parser definition so the generated parser will now correctly clean up those pointers in case of errors.
