Project setup fixes

[alesya-h]

Currently cloning a repo and runing lein auto-test leads to weird errors:

ERROR: cemerick.cljs.test was not required.

You can resolve this issue by ensuring [cemerick.cljs.test] appears
in the :require clause of your test suite namespaces.
Also make sure that your build has actually included any test files.

It turned out that this errors were due different versions of react being imported simultaneously (one from project.clj and other from om/reagent dependencies). After dropping react from project.clj it works fine.

[ckirkendall]

This needs to be handled but adding an exclusion to the reagent line not removing react from the project dependencies.

[alesya-h]

Updated pull-request. React dependencies are now just excluded from reagent and om, and com.facebook/react is dropped as it is deprecated and cljsjs/react should be used instead (see https://github.com/swannodette/react-cljs).
