Full DirectX 11 render with tessellation support

Recent changes:

• Tessellation support under DirectX 11.
• Tessellation support under OpenGL on ATI DirectX 10 level cards.
• Added hull and domain shaders for tessellation.
• Added "render_profiler" console variable that turns on/off performance profiling of render postprocesses.
• Fixed OpenCL initialization (headers were silently updated by Khronos Group).
• Detail textures can use the second UV channel (it can be selected in the "States / Options / Detail" drop-down menu).
• Added mesh_tessellation_base material for objects with hardware tessellation, it supports tessellation masks and height textures.
• Fixed UnigineScript bug with disappearing of "this" by complex inheritance.
• Reloading of meshes with different surfaces in MeshViewer; minor usability improvements.
• Added EXT_texture_snorm extension support.
• Added the distance for disabling occluders.
• Simplified SSAO for low shader profile.
• CUDA headers updated to version 2.30.
• Updated documentation on sound ("Principles of Operation / Sound" section of the manual).

By the way, this art asset will be used in our upcoming real-time demo, which is to be released in October.
