Fix problem found by pcOde that release-events from keys can happen to be 1ms later than the pressed event.

Added vertex *and* texture alpha to ONE_TEXTURE_BLEND material. Can be enabled/disabled via the pack function which handles all modes of this material. Default is texture alpha, as before.

Merge the two legacy ps_1_x work-arounds into one if block in order to avoid falling back to 1_x even if 2_x is supported. Thanks to DeM0nFiRe for help on this topic.

Support for vs_1_x with recent DX SDKs, but old gfx cards. This way the shaders are still compiled to vs_1_x, but need an extra dx dll. Hence it's not enabled by default, but may be opted in with the IrrCompileConfig _IRR_D3D_USE_LEGACY_HLSL_COMPILER

Added support for standard vertices, if no lightmaps are used. This saves lots of of memory and update times. But it needs some more testing, because I have not enough test files. Moreover, I've added some speedup for the vertex position loading with heavily reduced parsing efforts.

Fixed Deled texture search. The scene parameter DMF_USE_MATERIALS_DIR was renamed to DMF_IGNORE_MATERIALS_DIR with opposite meaning, because the default should be to use the directory defined in the file.

This fix should allow for more than 4 textures in SMaterial. Now, up to 8 are supported. We have to check for the texture matrix stuff if adding more could be simplified instead of adding more and more texture matrix defines. Maybe we also need to add a limitation for the numbers of texture matrices to create for systems using less than 8 textures. This patch has not been tested with all drivers so far, but seems to work ok.

Replaced file handling method by FileSystem versions. Changed readString to use a reference instead of return by value.

Fixed up version of the OpenGL ARB shader "parallax map and normal map with fog" patch. The code requires little changes to the ShaderMaterial in order to reuse existing shader renders, as we now have an array instead of one shader handle. Also, vertex and pixel shaders need to be adapted for fog usage, namely by setting the fogcoord in the vertex shader and adding a comment into which Irrlicht will add the proper fog option. Documentation will follow once we have cleaned up the shader usage.
