Make developer setup and user installation easier

The devdb project is now controlled by Maven, allowing Maven to
fetch the driver down and include it on our classpath.  This way
we save some steps in the install document.  Our mina_sshd fork
is also included in the appdist Maven project, ensuring it gets
built with the rest of Gerrit.
