[Bf-committers] Fixing Windows console

[Alexandr Kuznetsov]

Hi.

Blender on Windows starts as console app and hides the console few 
seconds after the start.

I reimlemmented, so Blender starts without any console. In addition, 
user can open console from Blender. The problem with this approach is 
that calling Blender.exe from cmd returns immediately. This might create 
some problems. I solved this by creating blendercmd.exe which set ups 
pipes properly and runs blendergui.exe, outputting as before. This might 
not be ideal solution for all.

Here some versions:
* Have only gui version

* Have blender.exe as a terminal pipe setter which runs blendergui.exe.

* Have blender.exe and and blendercmd.exe as a pipe setter.

For both make default shortcut for gui app.

* Redistribute two packages: one console app, another gui app. Make this 
a build option. (maybe we can even dynamically patch executable from one 
to another)

* Leave it as it is

Best,

Alex
