commit 4d7bbf81aa013d445a8ebf857d3ec60da4f61c04
Author: Karel Minarik <karmi@karmi.cz>

    PLUGIN RELOADING IMPLEMENTATION
    
    1. We need to set "config.reload_plugins" in environment.rb, it makes no difference in development.rb
    2. We must delete plugin's "lib" folder from ActiveSupport::Dependencies.load_once_paths
    3. We must reload plugin's "init.rb" in controller (using before_filter)
