Started Animat.UI and cleaned up dependencies a bit

Switched dependencies to `Json.Net` and `NLua` from DLL files to NuGet sources, so that the project folder is not so cluttered and all dependencies are automatically updated.

In order to build `Animat.UI` project, you will need to add the following NuGet source: `http://www.myget.org/F/wyvernzora/`. Just right-click on the solution, select `Manage NuGet Packages`, click on `Settings` button and add the source.
