Removed those extra CVS tag lines in the header files of ghost (now I know what

Removed the cocoa file since it was rubbish.

  * Interface for GHOST windows.
- * Dimensions are given in screen coordinates that are relative to the upper-left corner of the screen. 
+ *
+ * You can create a window with the system's GHOST_ISystem::createWindow 
+ * method.
+ * @see GHOST_ISystem#createWindow
+ *
+ * There are two coordinate systems:
+ * <ul>
+ * <li>The screen coordinate system. The origin of the screen is located in the
+ * upper left corner of the screen.</li> 
+ * <li>The client rectangle coordinate system. The client rectangle of a window
+ * is the area that is drawable by the application (excluding title bars etc.).
