#JC-1144: Added ability to block requests to plugin when
plugin is disabled. HandlerMapping stores information about
controllers provided by plugins and when plugin is disabled
it marks appropriate controller as inactive
#JC-1144 - Initial implementation of the question and answers view.

Implemented based on the mock-screen. Data is getting from the server
based on the "fake" Topic object. Only one "post" is displayed.

Next steps: improve design, add separate styles for question and answers
