Migrate to VS 2013 to benefit from the new Debugging and ISO C++11 features

- Have access to the ISO C++ cool features such as Variadic Templates and Initializer Lists
- Benefit from the VS enhanced IDE debugging, Intellisense and auto completion features as well as Build time optimization

How Verified:
- Linked my Bot with VS 2013 BWAPI libs/binaries
- Bot Tested and Verified on a clean XP SP3 (For the sake of AIIDE StarCraft 2014 competition) as well as Windows 8/8.1 and Win7 should be fine.
- No functional breakage observed (e.g Auto Menu)

Requirements:
For development: Visual Studio VC 2013 Express is enough. http://www.microsoft.com/en-us/download/details.aspx?id=40787
For running BWAPI Bots on non-development machines (e.g Tournaments clients): Install the VC 2013 Redistributable Package for non-development machines http://www.microsoft.com/en-us/download/details.aspx?id=40784
