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.
Ok, I got it. I missed overloading of ```-frameRate```. I will add change ```:target-frame-rate``` value inside ```quil.core/frame-rate``` fun.
