Update jsqlparser

[at88mph]

Current version is 0.9.5 (with a 0.9.6 snapshot). There have been API changes that will require some work.

The many bug fixes would be beneficial. Also, the current required version (0.6) is not in Maven.

Will update to latest as part of the work to move the parser into a separate module

Thanks. I did confirm that 0.9.5 fixes the issues with the count() function in the SELECT clause (i.e. count(distinct column)).
