Fix wrong wxStatusBar height in wxMSW in some circumstances.

Creating the status bar before the menu bar but associating it with the frame
after creating the menu bar resulted in a status bar of completely wrong height.
Fix this by enforcing the default height on the status bar when it's attached
to the frame.

Add wxThread::MSWGetHandle().

Under MSW a thread has both an ID, returned by wxThread::GetId(), and a
handle, which couldn't be retrieved so far. Add an accessor to do it.

Extract setup.h copying into a separate project for MSVC11+.

This fixes problems with parallel builds in Visual Studio 2012 or 2013 IDE as
multiple projects may try to copy setup.h file at once, resulting in errors.

Use _custom_build project as a common dependency to ensure that the copy step
is done only once.
