Base Framework rewriting

[brunnopleffken]

The current "MVC" pattern implemented in Addictive Community is just a mess. It's not completely object-oriented, and after implementing URL rewriting it became hard to write and maintain. So I decided to rewrite all the core-framework to make it more easy to write, maintain and extend.

Here is what WILL change:

• Controllers are now entirely object-oriented and has three basic methods: _BeforeFilter() (it runs before Main, e.g. authentication), Main() (the actual Main method) and _AfterFilter() (it runs after Main). There will be no more those large do-everything controller files;
• URL now follows the controller/id and controller/action/id pattern. So, accessing forum.com/thread/1 - without an specific action -, actually it runs Thread::Main(1). Accessing forum.com/thread/reply, it runs Thread::Reply(), and so on;
• No more blank templates or exit;. Inside a method, just write $this->layout = false to avoid page rendering. Useful for actions that returns JSON, manipulate MySQL data or any other back-end task;
• Will be possible and easier to create plugins and extensions for Addictive Community.

It'll take a while to be completed, but worth the job.
