Add example without cljx

It is difficult (no success, impossible?) to run cljx example in LightTable, so I just splited code into two sepate projects, one for client and one for server. I switched some dependencies to the latest versions and turned off transit parser (got exceptions from transit.clj)

Exceptions when run server with transit parser:
