Catch EmptyStackException and re-throw with a CQL error message #97

The ECQLParser uses java.util.Stack for parsing. If we get an exception from here (for example, if we used a CQL-reserved name in a CQL block) , we can narrow the cause down to CQL. This will make things a bit easier for people debugging such errors.
