Multi browser support *BACKWARD INCOMPATIBLE CHANGE*

Basically this will remove the browser and browserVersion from the config and replace it with a browsers array containing an array of browser objects. Example:

"browsers":[{"name":"firefox", "version":"30"},
			{"name":"chrome", "version":"35"}]

See the framework.conf for the default value, which you can override with an example like the one above. Observe that the framework, still, only supports webdriver creation for ie, firefox and chrome.

This will make it run each test on every browser configured in the browsers array, in separate independent tests and it will append the browser name and version at the end of the name of the test.
