-Fixed bugs in new 'blend operation' code, the 'if' checks on EBO_NONE could never return true, so everything was set to blend

-Fixed performance bug in CTerrainSceneNode, noticed that preRenderLODCalculations() is ran every render, instead of just when LOD data is recalculated.
  This increases the frame-rate on 'Terrain Rendering Example 12' from 410fps to 1300fps on my machine.

Fix png loader warning, also reordered transform calls such that only one test requires a late place after the read_update call. Added a test case which tests paletted png file loading and rendering.

Change type for stored and passed lights array. In most situations, only the ISceneNode was used, and the type is not necessarily ILightSceneNode anyway. So generalize this interface and the storage arrays internally.

The code needs to be cleaned up a little more. But it seems to work properly and is the preferred solution according to MSDN. Both solutions will be kept in the code, the choice define will be moved to IrrCompileConfig later.
