Bundle tools.nrepl in the bootstrap module [IMMUTANT-459]

We activation lein plugin middleware when reading a project in the
bootstrap runtime, and cider.nrepl loads a tools.nrepl namespace upon
activation. Normally, tools.nrepl will be available when running
normally under lein, so cider.nrepl does not have a runtime dependency
on it. However, in the bootstrap runtime, tools.nrepl won't be available
unless we explicitly bring it in.
Update jdbc integs to have clojure versions.

Without a clojure dependency in the project.clj, the apps' clojure
versions don't get updated by the fixture, and were all using clojure
1.3.0 brought in transitively by java.jdbc.
