D dropped in favour of C# for PSP emulator

[soywiz]

I just replied here with my motivations:
https://github.com/soywiz/pspemu/issues/1

"D is just fine to create an emulator. The problem was that I was 
doing emergent design, so I was refactoring a lot. And design 
flaws caused the refactorings to be massive. D didn't had a good 
IDE allowing refactoring by that moment (not sure about that 
now). That was the main reason for me to change the technology. 
Also there was minor flaws:
Compilation times were huge. I was using lot of compile-time code 
generation and at least at that time, that code was interpreted 
or not enought fast for me. Also I didn't get incremental 
compilation working, it failed everytime probably because that 
compilation-time stuff causing the compilation to take stuff like 
1 entire minute. And that was unacceptable too for me. I needed 
to run it lots of times to doing research. Also I needed a needed 
to chaneg the emulator to perform dynamic recompilation instead 
of just interpreting. With C# I could do portable dynarec very 
easily. In the case of D I would have to creaet a emitter per 
supported platform (mostly x86, x64 and ARM).

And my decission to use C# was not because I didn't like D. In 
fact, I liked D a lot, that much that I started an emulator using 
it."
