remove d3dx dependency, severely improve memory usage if necessary (#19)

* basic tga/hdr image loading

* bgr tga tex

* convert to dds during loading
doesn't work yet, fails to create textures from dds memory

* remove ext member from TextureFileStruct

* do not convert images, leads to weird loading problems...

* use regex matching for tpf loading

* convert non-RGBA images to RGBA

* remove d3dx (mostly)

* fix moving wrong image

* move TextureFunction to module

* move FileLoader to ModfileLoader module

* move TextureClient to module

* spaces

* ifdef debug

* 1.6.0

* compress images to dxt5 (bc3_unorm) to use less memory

* remove unnecessary directxtex source code patch

* don't move unnecessarily

* only compress if mods in filesystem use up more than 400mb

* use std::future to prepare to multithread image loading
fails when using std::launch::async though, maybe something in the directxtex library is not thread safe

* remove d3dx sdk from workflows

* remove extern "C"

* catch exception when saving texture

* make loading async (call CoInitializeEx)

* support DXGI_FORMAT_BC1_UNORM (DXT1) compressed textures without warning

* don't warn for BC2 BC4 or BC5 either

* update README.md
