Split out dll from the exe, so we can use the converter in another application.
Fixed including of COLLADA2GLTFExport.h so it works for projects including the library.
Add a reset to the ID generator so that if we convert a model multiple times we always get the same result.
Cleared the technique cache after the model is generated so we don't end up with a bloated cache when doing multiple conversions.
