Add support for nested table joins. This is a MySQL extension to the ANSI join
syntax which is omitted. Since the goal is full MySQL syntax support, this is
an important enhancement request.
There are plenty of examples on the listed documentation page to use as test
cases, as well as the example included in this report.
