Some tasks made little bit easier

In commits - little fix to CMakeLists.txt to support Visual Studio 2012 and added github repos as submodules.
libloadorder requires changes from https://github.com/WrinklyNinja/libloadorder/pull/7 to support Visual Studio 2012 from the box.
 
Plus included little bootstrap file, that prepares everything for building with Visual Studio (tested with 2012).

bootstrap.cmd must be run under "Developer Command Prompt for VS2012".
Bit later will make a pull request with updated docs, containing needed keys to CMAKE to build everything.
