Add displacements & planer mapping support (#29)

* Add displacement support to the base material.

* Refactor MF_OL_Layer for further customizations

Now we can understand what's going on here easily. So, this will help us to plug our new Material Base.

* Using our new Base Material for the landscape layer.

* Added displacement support for the landscape.

* Added missing files.

* Introduce edge displacement overrides

So now, we won't see any artifacts in between auto layer materials.

* Added tri planer support.

* Reduce the Tesselation factor on far distance.

This will reduce the frame rate drop dramatically.

* Add some performance improvements for planer mapping

Now, we no longer do planer mapping on the distance.
We do this by introducing it's own tiling parameters for planer mapping.
So, we can do the planer mapping & basic mapping at the same time.

* Add parallax support.

* Change some tiling options.

* Use the new layer for Mid

* Use new layer for all textures in auto layer

* Updated the default theme.

* Upgraded everything to use the new layer.

* Updated the Rock Material.

* Remove displacements from the default settings.

* Fix texture sampling issues

Uses BC1 (DXT1) for all color (with sRGB) & BC4 for other grayscale maps.

* Update the map.

* Update the mobile map

* Update mobile map lighting

* Improve mobile map's performance.

* Improved mobile performance in the mobile map.

* Updated Perf Tools.

* Finalized mobile support.

* Update DefaultEngine.ini

* Updated fog.

* Updated new base material & the rock material.

* Add slope displacements.

* Added displacement support for slope

* Finished migrating layers.

* Updated all the materials to new changes.

* Updated textures.

* Update maps.
