Change entry point for WinRT apps to WinMain

Using wmain causes the problem that the linker seems to create some code
around it, which calls ExitProcess. That function however is forbidden by
the Windows Store Certification process and hence you cannot publish an
application currently. This does not apply to Windows Phone, which links
in such a way that this problem does not occur there.

With WinMain as the entry point this does not happen and also is the
default entry point. Testing locally shows that certification goes fine.
Since it does not pass the full command line string, the C-runtime method
__getmainargs is used instead. This also gives access to any environment
strings which may be passed.

Note that MSDN states that this function should only be used for desktop
applications. For XAML/C++ scenarios there is no entry function at all,
but rather the App object gets instantiated in the default template. But
this only works for XAML itself and not for plain C++ applications,
probably some other entry wrapper is created on the fly here.
