Native GTK bindings v2

[timotheecour]

Have you tested it on osx?
I get lots of errors such as Error: module Atk from file 
gtk2/atk.d conflicts with another module Atk from file gtk2/atk.d 
etc...
I'm wondering whether it's due to case insensitivity on 
OSX/windows. I thought the convention was to use all lowercase 
for module names. As it is it seems to create collisions. Also 
there were a few other errors which I had tweak for eg:

phobos/std/bitmanip.d(66): Error: shift by 32 is outside the 
range 0..31
phobos/std/bitmanip.d(149): Error: template instance 
std.bitmanip.createAccessors!("_mantissa_low_mantissa_high_biased_exponent_sign",uint,"mantissa_low",32,0u) 
error instantiating
phobos/std/bitmanip.d(203):        instantiated from here: 
createFields!("_mantissa_low_mantissa_high_biased_exponent_sign",0,uint,"mantissa_low",32,uint,"mantissa_high",20,uint,"biased_exponent",11,uint,"sign",1)
.../girtod/gtk2/glib2.d(3528):        instantiated from here: 
bitfields!(uint,"mantissa_low",32,uint,"mantissa_high",20,uint,"biased_exponent",11,uint,"sign",1)
