remove the msvc directory in order to create a git module instead
Added submodule with MSVC++ 2012 prebuilt libraries

A submodule used instead of direct way of putting files into a repository
so that the official repo won't grow too much in size and since MSVC++
dependencies are not typically needed (on Linux/Mac and Windows with MinGW).

For those who don't need MSVC++ libs, they should just ignore the submodule.

Those who'd like to play with MSVC++ build should invoke:

git submodule init
git submodule update
Created a VS2012 project and solution for GoldenDict

It uses excellent Visual Studio extensions for Qt,
written by Adam Badura (@adambadura). Many thanks!

The project file is fully functional in Release-Qt4 configuration,
for both x32 and x64 architectures.

I decided not to use the official Qt Plugin, since it
generates HUGE and broken project files which is painful
to maintain.

Here we have a pure visual studio solution with proper
Visual Studio extensions to support Qt-based development.

These extensions cover RCC, Lrelease, MOC and UIC,
automagically invoking them when needed, with basically
no need for manual steps to maintain.

Also, GoldenDict can be built from the command line as well,
no Visual Studio is required:

For Win32:
MSBuild /m goldendict.sln /v:m /nologo /p:Configuration=Release-Qt4 /p:Platform=win32

For x64:
MSBuild /m goldendict.sln /v:m /nologo /p:Configuration=Release-Qt4 /p:Platform=x64
