TileRenderer*: TileRendererNotify -> TileRendererListener w/ clarifying functionality (reshapeTile(..), ..); Only process GLEventListener impl. TileRendererListener; attachToAutoDrawable -> attachAutoDrawable, etc.

-TileRendererNotify -> TileRendererListener
  - Added methods:
    - void reshapeTile(TileRendererBase tr,int tileX, int tileY, int tileWidth, int tileHeight, int imageWidth, int imageHeight);
    - void startTileRendering(TileRendererBase tr);
    - void endTileRendering(TileRendererBase tr);

  allowing to clarify user code and API specification,
  i.e. TR only processes GLEventListener which impl. TileRendererListener.

  This also allows simplifying the API doc, while having a more descriptive
  reshape method focusing solely on tile rendering.

  Further more, the start/end TR methods allow certain GL related actions
  while the context is current before and after iterating through the tiles.
  This is even used for RandomTileRenderer (one tile only), to allow
  to reuse same TileRendererListener for diff TRs.

- Fix language, attach and detach usage was vice versa. We do attach an GLAutoDrawable to a TR
  - attachToAutoDrawable -> attachAutoDrawable
  - detachFromAutoDrawable -> detachAutoDrawable

- Adapted unit tests.
