* process navigationOptions colors
* created a test for new RNNRootViewController functionality
* changed RNNRootViewController to init with name, navigationOptions and container id, instead of node
* changed RNNRootViewController to get a new type - RNNavigationOptions
* refactored statusBarHidden test and implementation, all tests pass
* added setup to RNNRootViewControllerTest.m and refactored tests
* added test for title and implemented static title
* minor fixes

* added topBarTextColor to RNNNavigationOptions
* topBarTextColor RNNRootViewController test
* changed setOptions to receive RNNNavigationOptions. created OptionsProcessor to process colors in both layoutTreeCrawler and Commands
* minor fix
* create setOptionsDynamically in RNNNavigationOptions to make dynamic options merge with static option instead of overriding them
