wined3d: Map D3DFMT_L16, D3DFMT_A16B16G16R16 to OpenGL formats. Map: D3DFMT_L16 -> GL_LUMINANCE16_EXT D3DFMT_A16B16G16R16 -> GL_RGBA16_EXT as Raphael suggested. Also increase the returned Bpp for unknown and unhandled formats from 4 to 8 bytes - this part fixes segfault in the F.E.A.R demo. It now shows some flashy graphics before it dies again :)
