Interface for all StreamDriver (WMSDriver, WFSDriver ...)
Now we can get the best suitable StreamDriver. Thoose drivers (WMSDriver, WFSDriver ...) will be out later.
Add StreamSource to gdms. It's base on WMSSource and we can use it for others stream like WFS. Some methods aren't implemented yet.
Add register for StreamSource. WMSSource will be obselete.

clean up sources, add headers.
Change the way to register the stream. We used a WMSSource while now we use a more generic class, StreamDefinition.
move classes around.
Simply adding que WMS driver class to the project to complete the structure
cleanup and headers.
Add StreamSourceAdapter and StreamReadWriteDriver.
Rename StreamSourceAdapter to StreamDataSourceAdapter and modify createDataSource from StreamSourceDefinition.

Create a simple WMS Driver to test our classes. Seems to work :) There's a lot of work to do now to improve driver system, layer manipulation and connection.
