Added repack

I added lein-repack as a plugin

you can install all the components seperately by running:

    lein repack install

and deploy all the components to clojars via

   lein repack deploy

Then use them as seperate dependencies by including them in your project.clj:

[system.core "0.1.1"
[system.components.h2 "0.1.1"]
[system.components.datomic "0.1.1"]
etc...
