Compilation for MSVC2013, thanks @dalkon

OTclient now compiles in "Microsoft Visual Studio 2013 Express for Windows Desktop"
All the needed libraries you can download at https://www.dropbox.com/s/2yfb1c763io8efy/otclient-msvc13-libs.zip
NOTE: You have to change VC++ Directories to the properly directories
NOTE: Latested MSVC 2013 or greated is required
