Plugin System

My Plugin System
--------------------------
(Short Information: When you look at "Files Changed" you will see whole files deleted and created again. I think this is a fail of my Git Client, in the "config.php" only one line was edited!)

The very very simple Plugin System I wrote bases on the principle of "Hooks" ( **And** can be disabled the same way!).

But it has 3 advantages:
- You can define and fire your own hook points
- It is easier for third-party-developers to create additions/mods to your application
- They can be installed by everyone, even if he has no idea of programming
