Cross-platform tests for Quil

To run tests use:

1. ```lein clean```
2. Compile it:
   a. ```lein with-prifile test-1.5.1 compile``` for Clojure 1.5.1
   b. ```lein with-prifile test-1.6.0 compile``` for Clojure 1.6.0

3. Open ```test\html\test.html``` and push ```run``` button


You can see results on html page. You find errors in browser dev console.
Let's continue our discussion.
In cljs these atoms never changed so there is not point of having atoms in the first place. If later we'll be changing it - will add atoms then. No need to add something which is not used "for future".
