f1b5bc3831 Use references to images from image loader. 
In general, we should really copy the images with the built-in Clone()
function, but then we'd need to manage memory, etc. To avoid that headache,
we can simply just use references.

479ba8e76d Fix a bunch of MSVC compiler warnings and errors. 
Most notably, we need to actually fix a bug in MSVC that doesn't know how to properly instantiate
enums in partial template specialization. There are more details outlined here:

http://stackoverflow.com/questions/15466594/why-does-msvc-fail-to-compile-this-template-function

The fix in this commit closes #10

Also in this commit is a hacky way to allow GL defines. Apparently "LoadImage" is defined as a
macro even with WIN32_LEAN_AND_MEAN. This means that we have to #undef the code that includes
it, meaning that we also need to make sure not to actually mix GLDefines.h with any file that needs
to use the functions from Windows.h

dd41fc6ba1 Finish first pass of ASTC decompressor 
Added color unquantization, the partition selection function, and the
actual lerping of colors once the texels have been decoded.

1f5cb9294c Add ASTCEncoder tests 
Start with small tests to make sure that integer sequence encoding is working the way
that it needs to. Ideally there will be many more tests here, but for now we are trying
to get ASTC decompression working and testing is not a priority.

5a68febdda More work on ASTC decode. 
Fixed the notion that the CEM data was right after the first six bits
after the partition mode. It's actually right before the texel weight
data. Still not sure whether or not the texel weights are read in
the opposite order from the color data...

Also, added some preliminary integer sequence decoding. This will need
to be tested before we actually figure out if we did it correctly or not...
